THEME Designing Future Society For Our Lives
World Expo 2025 aims to provide humankind with an opportunity to return to life as a starting point, rebuild awareness of the life of each other and take a careful look at life in diverse forms the natural world to explore a sustainable future of the world. It endeavour to give a realistic picture of a future living not just through thought but also through action.
In other words, a straightforward question is being asked to everyone, what do we perceive in future living?
Presently, nature ecosystem is declining globally at rates unprecedented in human history with grave impacts on people around the world now likely. The health of ecosystems on which we and all other species depend is deteriorating more rapidly than ever, eroding the very foundation of our economics, livelihoods, food security, health and quality of life worldwide. However, it is not too late to make a difference, but only if we start now at every level from local to global.
Locally, Malaysia is a beautiful country as it has many things to offer. It is often known for its multi-ethnic, multi-religious and diverse cultures but what makes Malaysia truly special is the country’s natural beauty. Having one of the most complex tropical rainforest ecosystems in the world, representing the pinnacle of life on earth that helps in mitigating global climate change.
KEY ELEMENTS
Three distinctive key elements emphasize in the design are: abstract, iconic and green technology. Developing the nature elements in an abstract way to create an iconic Malaysia inspired design, while integrating green technology approach in terms of building materials and construction method.
Past
Future
Present
In the effort of designing a pavilion with Malaysia identity, the design concept was to look back at the past, appreciating the mighty of nature and how the nature resources had contributing to the presence-built environment and it’s time now for us designer to attempt on design a future of built environment to protect our wounded nature, a reversed ecosystem corresponding to UNESCO World Heritage Emblem.
02 Rich ecosystem allows human habitat to grow and form their own private spaces
03
Over the years, modernism starts to take over hence the natural ecosystem is forced to adapt, change to co-exist
Aim: To create architecture that represent Malaysia while allowing natural ecosystem to inhabit within modern built environment
INSPIRATION
The reversed ecosystem is greatly reflected in our core inspiration, Pinnacles of Gunung Mulu, Sarawak. One of the most natural wonders in Malaysia, and UNESCO Heritage Site.
Both the nature and the skyscrapers of the city punching into the skyline sharing the similar expression, however it can also be seen as “same but different”. This inspires our designed pavilion to be a dynamic and striking combination of Malaysia nature and technology.
“AlwayslookbackatthenatureasithasalwaysbeenasettingimageandprominentcharacterofMalaysia, andlettingthenatureforeverremindingyoutobehumble.”
The pinnacles have been formed in the limestone which occurs on the valleys from water percolating through soil. Over the past 50 million years, the soil which once covered the limestone have been washed away exposing the pinnacled surface of the limestone mountains. Presence of the formation of pinnacles has encompasses incredible caves and karst formations in a mountainous equatorial rainforest setting, providing significant natural habitat for a wide range of plant and animal diversity both above and below ground.
The formation of Pinnacles of Gunung Mulu symbolic the future built environment that we tend to design, and with that being formed it allows a natural ecosystem to form in the setting which resemble the nature.

BUILDING MATERIALS
Suspended Tensile Roof
Tensile membrane roof systems is an ideal solution for passive cooling as it block out UV rays and reduce energy consumption from ac units. Additionally, tension fabrics brings in natural light, reducing the need for artificial lighting and thus reducing energy use.
● Reducing construction and waste costs as it is a simple way to construct for 6-months exhibition.
● Minimal environmental impact and affordable cost.
● The tensile fabric can be repurpose which automatically be more economical as well as eco-friendly choice.
● Tensile roof are suitable for four season country as long as the canopy is properly engineered. (spring,summer, autumnMay-NovduringOsakaExpo2025)
Rectangular Truss Frame

Sustainable Usage of Space
Hybrid spaces are a popular solution that has been on the rise due to the pandemic. It refers to creating spaces that serve two or more functions which can be switched back and forth according to the activity of space, or according to the time of the day.
● Partnered with movable screens or convertible furniture, allowing the space to be dynamic and multi-functional without increasing any floor area.
Natural Ventilation & Lighting
With the usage of suspended tensile roof, incorporating natural ventilation and allowing natural daylighting into the pavilion decreases energy use and the associated greenhouse gas emission of the pavilion.
● Gives better humidity control, improve air quality and reduces carbon emissions.
● Lower operating and maintaining costs.
Green Landscape
Landscape and architecture design to support each other by allowing the extending interior space to the exterior, which increases the use of both. Landscape also creates a natural environment around the pavilion, giving the occupants a healthy breath, good appearance and natural beauty.
● Plants can purify the air in within the pavilion, filtering wind and noise.
● Stabilise the microclimate and provide beneficial contact with nature.
Rainwater Harvesting System
Rainwater is collected through the openings of the tensile roof and rainwater harvesting system to promote self-sufficiency of the building while integrating with an irrigation system for the landscapes and toilets.
● Irrigations of a large patch of landscape leads to lowering the surface temperature of the pavilion, causing lower thermal gradients between surface and air.

● Summary
Bracings
The column cross bracing is placed between two adjacent columns to increase lateral rigidity, transmit horizontal force, and assure the overall stability of the building structure. They prevent from excessive sidesway caused by lateral loads brought about by wind or earthquakes.
Rectangular Truss System
Rectangular truss can be used as bending resistant spans at a free span of up to 30m with high load bearing capacity. Due to its special shape and dimensions, the rectangular truss exhibits a great rigidity and can thus be used for long spans with high loadings compared to a single steel column.
They are fast and cost-effective to install and do not require heavy expensive equipment or excessive preparation in order to be used effectively. Trusses are generally built in a factory and delivered as a complete set to a job site, where the structure is then built.
Built-up Column
The columns in tall industrial structures that support heavy loads are constructed of built-up sections. Built-up columns frequently consist of HE or UPE sections with battens (flat plate) or lacing (typically angles) welded across the flanges. Built-up column buildings are almost always highly loaded and frequently vulnerable to moving loads from cranes.
In our situation, a built-up column can support a rectangular truss that is being subjected to shifting loads from a cable. Instead of utilizing a single steel column, a built-up column has a larger cross-section moment of inertia due to the space between the chord centroids. This raises both the axial force and bending moment capacities of the column while lowering its slenderness ratio.
Advantages
Lightweight
The steel used in the rectangular truss structure is a high-strength lightweight structure.
Low cost and easy to construct
Steel truss can be built from simple prefabricated units, which are often of standard size and shape.
For large span structure
Truss systems can span large distances and dissipate forces throughout the structure with load-bearing only at the ends.

Load Transfer
Load from hoist machine
The load from the tensile fabric roof will be carried by the cable. The roof load is acting downward, it causes the tension force pulls equally on the opposite side of the cable. The tension force will be delivered to the truss structure.
Load Determination
1.Loading analysis in each cable
Dead Load
Selfweight of hoist machine = 1.0kN
Selfweight of tensile membrane = 2.0kN
Weight of rainwater = 11.25kN (Allowable volume that can be carried by the tensile membrane = 4500 litre)
Total dead load carried by each cable = 14.25kN
2.Surface load on truss structure
Dead Load
Selfweight of solar panel = 0.25kN/m²
Imposed Load
0.6kN/m²
The load from the cable will pull the truss structure inwards. In addition, the load from the solar panel also acting on top of the truss structure. The truss structure section is able to withstand the tension force from cable and compression force from the solar panel.

Wind Load
Windiest month of the year in Osaka is February, with an average hourly wind speed of 4.2 m/s.
Analysis of wind load using analytical procedure. In our case, the structure does not satisfy the conditions for using the simplified procedure. Therefore, the wind load is calculated using the analytical procedure as it is a regular shaped structure, and it does not have response characteristics making it subject to across-wind loading, vortex shedding, instability due to galloping or flutter, or does not have a site location that require special consideration. The steps of analytical procedure are described in ASCE 7 Section 6.5.3.

Seismic Design
1. Bracings
Bracing in vertical planes (between rows of columns) creates load channels for lateral stability and for transferring horizontal forces to the ground. Cross bracing is used to keep structures stable during seismic occurrences like earthquakes as well as when the wind blows. Additionally, it restricts lateral movement of the building, lessening the risk of cladding and component damage. Cross bracing typically consists of diagonal elements positioned in an X-shape in a vertical plane and is made from steel rods, angles, or tubes. Normally, cross bracing is situated parallel to a building's columns.
Earthquake Load
Osaka, Japan is in high seismicity region. On June 18, 2018, an inland crustal earthquake measuring MJMA 6.1 struck Japan's Osaka basin. The highest PGA for this event was greater than 0.9 g, and it was followed by several lesser aftershocks.
Response spectrum method is used to examine the elastic and inelastic response behaviour of the structure.
Friction Dampers function as a reusable fuse that simultaneously releases energy. No replacement is required after an earthquake event. Therefore, the building can endure an earthquake without suffering serious structural damage.
By creating friction through a spinning friction joint, a rotational friction damper decreases seismic energy. They dissipate the input energy of earthquakes through friction in their rotating plates.
DETAILS OF STEEL FRAME STRUCTURE
Steel Section Size
FOUNDATION OF THE STRUCTURE
Note: All dimension in mm
Foundation Element
● 3 piles group is selected as the foundation element for the structure.
● The dimension of pile is 200mm x 200mm.
● Each pile has working load value of 450kN. However, 80% of the working load is used as the pile bearing capacity (0.8 x 450kN = 360kN).
● the soil bearing capacity is assumed as 200 kN/m3
Note: All dimension in cm
DETAILS OF STEEL FRAME STRUCTURE
Base Plate
Elevation
Loads from steel columns are transferred through a steel base plate to large area of the pile cap. The base plate are welded directly to the columns. The base plate is larger than the column size to provide room for the placement of the anchor bolt holes outside of the column.
OTHER COMPONENTS
1. Hoisting system
● Electric Chain Hoist
Our hoisting system uses a 2 tonne electric chain hoist with remote control since our tensile membrane needs machinery to move vertically. The analysis of loads is shown below.
Dead load carried by each machine:
Self weight of tensile membrane
Total weight of tensile membrane = 13.387kN / 9
cables = 1.5 kN ≈ 2.0 kN
Weight of rainwater = 11.25kN
Total dead load = 13.25kN (less than 2 tonnes)
2. Wire Ropes for Tensile Structure
● Cable to Machine Connection
This type of connection is used to connect the hoist machine to the cable by creating a hook to carry the machine. Bolt grade 8.8 is used to overcome high tensile and shear stress.
A 19 strands rotation-resistant rope is adopted in the cable system of our tensile membrane. A core strand is surrounded by six strands in one direction, and 12 strands are then arranged around this initial operation in the reverse way. This kind of rope provides greater crushing resistance, a higher strength-to-diameter, resistance to bending fatigue, and outstanding stability because of its tightly compacted smooth structure. Therefore, it is suitable to be used in our cable system to carry the hoist machine.
OTHER COMPONENTS
3. Tensile Membrane
Polypropylene is used as the material of the tensile membrane. It is water and stain repellent, resistant to mould, moths and bacteria and is extremely resistant to acids and alkalis. It is also resistant to humidity and weathering. It doesn’t absorb water and dries quickly.
4. End Connections for Tensile Structure
● Cable to steel frame connection
● Foundation connections
U-bolt wire rope clip
Wire rope clips can be used to form a load bearing eye at the end of a cable or wire rope, or to connect two cables together with a lap splice.
Turnbuckle
A turnbuckle is a common rigging device that is used to adjust tension and reduce slack in a rope, cable, or similar tensioning assembly.
The connection can be direct to the foundation or be made with fixing brackets. Fully locked wire ropes are normally bolted with forked sockets to a fixing bracket. The tolerance can be compensated using a mortar layer under the fixing bracket.

STATIC SUPPORT
The Static Support is screwed to the underside of the wooden beam and pushed onto the shaft of the GTS.
JAPANESE CEDAR TREE
Japanese cedar is a woody, needled evergreen tree that is indigenous to central and southern Japan as well as China. It is a member of the Cupressaceae (cypress) family. It may be conical to pyramidal in shape, 50 to 70 feet tall, and 20 to 30 feet wide.
Distance Rings are used to determine the exact position and the distance to the tree.
DISTANCE RINGSTREE HOUSE PLATFORM
Due to the high tension in the bridge cables, they should be fixed to a sufficiently strong point on the tree.
Eye bolts in the style of lag bolts (ie a 6-8" threaded section), should be fitted at 45-90° to the direction of pull. This lowers the risk of the bolt pulling out under load.
Long bolts passing all the way through the tree can take much higher loads because they can be lined up with the cable.

Inter-column connection
The connections include an additional steel plate and resilient layers to provide improved ductility and seismic energy dissipation. The ability to dismantle the connection and separate the modules is one benefit of employing bolted connections in steel modular structures.
Steel connector plate
Since the connector plate and column end plates do not come into touch with one another to create friction, the main method of weight transfer in this connection is through bolt bearing. This extra plate is expected to deform and contribute to the connection's overall energy dissipation, which will significantly lessen the seismic energy that is sent to the modules.
Resilient material
Between the steel connector plate and steel column plates is an elastic material with a shear modulus of 0.3 MPa, such as rubber. This connection can be categorised as a friction-type connection since the connector plate and resilient layers experience force transmission as a result of the resulting friction. The system will receive additional dampening from the robust layers, reducing the need for significant connector plate deformation.
