LUTHAN ARANIRY AHMAD

UNDERGRADUATE STUDENT OF ARCHITECTURE INSTITUT TEKNOLOGI BANDUNG A highly motivated student, have a strong commitment to achieving my goals with hard work and consistency. I’ve been trained to make strong conceptual designs and out-of-the-box ideas through my educational experiences.

I am also able to manage a team and work under pressure which I learned through my organizational experiences.

“When a student comes to me with great ideas and passionate about his/her design, it incites me as supervisor to assist the student to do his/her best. I experienced this with Luthan in three buildings he designed in this course.

Inverted tent structure is not an easy structure, but he did his model very well. The combination between hypar structure and folding plate in his last project created a simple but incredible space inside. You did a great job, congratulation!”

WATCHTOWER IN THE RAINFOREST FRAME SYSTEM I RECIPROCAL FRAME

PROJECT DESCRIPTION Location: Cameroon Structure System: Frame System Structure Classification: Reciprocal Frame Material: Glue Laminated Wood Watchtower In The Rainforest is a bird-watching tower that is provided for tourists. It is located in the middle of the rainforest of Cameroon and far away from the settlement which makes it the best spot for bird-watching. Cameroon is the richest country in West Africa for birds, 968 bird species live in this country. This variety of the bird species makes cameroon one of the best place for bird watchers.

CONCEPT RECIPROCAL FRAME + TENSION + RECIPROCAL ROOF The main concept of the watchtower is to combine reciprocal frame, tension, and reciprocal roof. The idea is to create a simple module which is then assembled to produce a magnificent form. The glulam wood material is chosen because it has sufficient tensile strength and elasticity, the wood structure also gives a natural impression so that it blends with the environmental landscape.

STRUCTURALLY SOUNDED

NATURAL LIGHTING AND VENTILATION

The watchtower is designed without walls to show the structure more clearly, so that the glulam wood structure can be seen from every side. The ground floor is designed with an amphitheater to widen the visibility of the reciprocal frame, so that structure will looks more impressive when viewed from below.

Since the watchtower is designed without walls, it is able to maximize natural lighting and cross ventilation. The location of the watchtower is in the middle of the rainforest so that the air and natural light are in good condition to be utilized.

STRUCTURE SYSTEM AND COMPONENTS The structure system is using frame system: reciprocal frame.

The main structural components use 24 glulam rods 30m long with dimension size of 30x40cm. The glulam rod is supported by a tensile force using a 4cm diameter steel cable.

Distribution of Structural Components 1. Module X: 16 rods of glulam 2. Reciprocal Roof: 8 rods of glulam 3. Pull Cables: 8 steel cables Watchtower in the Rainforest I 9

a shelter in sahara form-active I tent structure

PROJECT DESCRIPTION Location: Egypt Structure System: Form-active Structure Classification: Tent Structure Material: Membrane A Shelter in Sahara is a resting point for tourists who travel in Sahara. The visitors can take a rest in this shelter while enjoying the beautiful sunset in the desert. The shelter is located in a Sahara tourist destination in the desert of Egypt. Tents are usually used in the deserts because they allow air to circulate within them, keeping them cool in the desert. The structure of the shelter uses a majestic tent structure which can give the impression of a tent in a modern way.

CONCEPT NORMAL TENT STRUCTURE + REVERSE TENT STRUCTURE The basic concept of this shelter is the combination of the normal tent structure which a curve-down membrane and the reverse tent structure which a curve-up membrane.

STRUCTURE LAYERS

MAXIMIZE SPACE

The shelter is designed with a circular structural layer. there are two layers of structure, the inner circle structure layer is a normal tent structure, and the outer circle structure layer is a reverse tent structure.

The shelter is designed with a single mast in the center and free of supporting mast in the surrounding area so that each side of the building can be used more freely.

18 I A Shelter in Sahara

STRUCTURE SYSTEM AND COMPONENTS The structural system is using form-active: tent structure system. The main structural components use a steel mast 20 meters long, a membrane as the building envelope, and steel cables as a tensile element in the building.

savanna visitor center

surface-active I folded plate structure

PROJECT DESCRIPTION Location: Kenya Structure System: Surface-active Structure Classification: Folded Plate Structure Material: Glue Laminated Wood Savanna Visitor Center is an information center for tourists in the savanna tourism park. The visitor center is located in the savanna of Kenya. Savanna is a grassland ecosystem characterized by the trees being sufficiently widely spaced. The Savanna of Kenya is one of the beautiful savannas in Africa because it offers the most diverse scenery with a surrounding of Mountain Kilimanjaro and also a variety of animal species, especially the elephant of Kenya.

CONCEPT FOLDED PLATE STRUCTURE + SHELL STRUCTURE The basic form of the visitor center is designed through a sheet of paper that is folded according to space requirements. The module formed by the folding structure is combined with Shell Structures: Saddle Shells which gives a strong impression on the surface structure of the hypar. This combination is seen in building structures that are folded and also curved, different from folding structures in general which rely on their strength only from the shape of the folds, this structure design can rely on their strength from the shape of the folds and also the curvature.

HYPAR SURFACES STRUCTURE

STRUCTURALLY SOUNDED

Hyperbolic Paraboloid (Hypar) Surface Structure is included in the category of Shell Structures: Saddle Shells that rely on the strength of their curvature. The curvature produced

by Hypar Surface Structure is able to reduce the tendency of the structure to be deformed when given a load. The addition of the Hypar Surface Structure system can increase the strength of the building.

Hypar Surface Structure is commonly used on roof structures, but the building design is designed with a wall structure that also uses Hypar Surface Structure. So that the entire structure in the building uses the same structural system and the Hypar Surface Structure can be seen clearly.

IN TUNE WITH NATURE

MAXIMIZE SPACE

Hypar Structure Surface gives a dynamic shape to the building due to the curvature it makes, The dynamic form will make the building blend with the environmental landscape.

The material used is a combination of glulam wood and glass material which have the same tone as the surrounding landscape

Through the folding strength and curvature of the Hypar Surface Structure, the building design is able to support its own load, so that no additional supporting structure is needed on the inside. Therefore, the activities that occur in the space in the building can be carried out more optimally.

28 I Savanna Visitor Center

STRUCTURE SYSTEM AND COMPONENTS The structural system is using surface-active: folded plate structure. The main structural components use glulam rods which are joined to form a hypar surface. There are 48 hypar surface modules measuring 3 x 6 meters that are used in the building design.

BUILD METHOD

The rods that were originally separated are joined using the glulam technique to form a curvature in the module and create the Hypar Surface.

Modules at the bottom are installed first and connect the modules into the pedestal.

The next module is connected to the lower module until it reaches the upper module.

The upper modules are connected by a single-joint bending system.

Adding aluminum frames for the glass and also a floor plate to accommodate the activities inside.
