WEEK ONE: Studio Activity - A compression
1. Compression (YouTube, 2014) - Heavy, overlapping modules, stable, self supporting
like structure that was created in studio time, - Here it is evident that the material is compacting together - we used a modular method of building in compression which is similar to masonry work
!
Materials best used in compression: • concrete • masonry/brick work • stone • hay bail (also works in tension) • ice blocks • termite mound Tower Building - Used compression method in order to create a stable, self supporting building - The modular method allows the load weight to be spread out and therefore is stronger and better balanced - Decided circular building structure would be easier to build higher due t the fact that you can taper it in as this cant be done in a rectangle structure
!
Planning: - we started off wanting to create a circular structure which we wanted to taper in , however we have made the radius to big therefore we made it a semi-circle
WEEK ONE: Studio  
Load Paths - the load path shows how the modular method of compression creates an equal weight distribution, increased strength in the building - this method was so successful that even when blocks were removed the tower held its shape - these loads would be dead loads as it is the structural part of the building they create the support structure - the live load could be when adding another block to the tower you had to ensure it was placed properly to ensure the weight distribution was even and the weight of the load were carried down following the same pattern as before
WEEK ONE: Studio   Other Groups -Group 3 also used this modular method of compression as it proved the most successful way to construct a tall tower -this group created the tallest tower and did what we hoped to do which was tapper the tower upwards so it become skinnier as it got higher
Group 3:
Group 2:
- the wooden blocks used -
-
- group 2 didn’t use the
same type of method as us and group 3, they stacked there blocks in the same modular method however they didn't stacked them flat - this proved not as strong as the tower got higher and it resulted in them not building a tower us high as the other ones
Material
were medium to light weight material they proved stronger if they were used horizontally rather than vertically as the weight was spread out more efficiently our tower reached a height of about 1.6m and we had to stop due to the lack of blocks left !
Results - the building method we used proved very effective and held the weight of our tower - we were restricted on how high we could go due to the fact that we ran out of blocks - to test the strength of the building once completed we pulled blocks from different sections of the building to see it if would cause sit to collapse - We resulted to throwing blocks at the tower and as seen in the figure to the right it held its shape surprisingly well. - the modular method of construction seemed to be the best method of distributing the weight of the blocks

WEEK ONE: Learning Loop Forces (Newton, 2014). 1. tension: pulled 2. compression: pushed * for every force there is an equal and opposite reaction: equilibrium
Types Loads (Ching, 1975) • Live loads: moving or moveable loads on a structure, acts vertically downward but may act horizontally to reflect dynamic nature of moving load, collects snow, water (Ching, 1975) • Impact loads: short duration due to equipment and machinery, treated as a static load due to its dynamic nature that amplifies static load (Ching, 1975) • Dead loads:static loads acting vertically downwards on a structure, comprise on self weight of the structure, permanently attached fixtures
- tension forces:
external load pulls on a Materials (YouTube, 2014) structural member, particles composing the material move Different properties apart and undergo tension = stretch material (amount • strength: strong, weak (steel, wood) depends on stiffness, amount of stress and weight of load • stiffness: floppy, flexible, stretchy - compression forces: opposite effect of a tension force, (rubber, nylon, concreate) external load pushes on a structural member, the • Shape: mono dimensional (linear), bi particles of the material compact together = shorter dimensional (planar), tridimensional material (volumetric) • Behaviours: isotropic (similar no matter what direction force), anisotropic Loads (Ching, economy and sustainability: distance to • 1975) transport, environmental friendly, 1.static: efficiency, readily availability • applied slowly materials, cost
2. dynamic - applied suddenly to a structure, rapid changes in magnitude and at point load - two major types: earthquake and wind Types of loads: 1. gravity 2. wind 3. earthquake

Site analysis (Ching, 1975) - Site analyse is the process of studying contextual forces that influence how people might situate a building, layout, shape, relationship with landscape and position its spaces: conducted through site surveys that gathers into at physical site
WEEK ONE: Glossary and References Key Terms: (Ching, 1975) (YouTube, 2014) • Force:anything that producing magnitude and direction that causes a change in shape or movement to something • Compression: due to the load the structure compacts causing the material to shorten • Reaction force (Fr):opposite and equal response to a force • Point load: where the force is applied and most intense • Beam: a structural element that helps support a structure • Load path:the direction the force travels through the structure/ material • Masonry: a brick work that uses compression to create strength and support through a module overlapping pattern
