The design of the bus shelter is inspired posture of flying bird. Therefore, dynamic form was derive from the motion of the wing of bird which extended outward.The design of the bus shelter consists of 2 basic geometry forms, which is tetrahedrons and cuboid. The two tetrahedrons attach together to form the roof while the cuboid form the space beneath the roof.

DESIGN CONCEPT AND INSPIRATION 01

The roof is designed to shade both part of the bus shelter, as the seats is provided in 2 direction to accommodate more peoples. Double pitch roof allow shading from different direction while not obstructing the wind flow. Moreover, it increase the rate of rainwater discharge.

DEFORMED DOUBLE PITCH ROOF

I NTRODUCTION

FOREST SHELTER

Unobstructed structures which

provide good ventilation, natural

lighting and huge activity spaces. High accessibility, can be entered through all

directions.

Roof is designed to enhance the airflow within the spaces of bus shelter. Large overhangs shade the shelter but letting natural lights in at the same time.

PRECEDENT STUDY 02

The materials and type of construction used are able to prevent the structure from being deformed by lateral forces

such as winds and earthquake.

WEATHER RESISTANT AND TEMPORALITY 04

The structure of the roof is designed to prevent the rainwater from flowing into the shelter, the material of the roof itself is also

waterproofing so that the water will not leak

through the roof into the shelter.

The structure is designed to last for an approximate lifespan of 5 years, making

its presence temporary.

LOAD AND FORCES DISTRIBUTION 03

plan view elevation

There are 3 columns align in a row serve as main support of the bus shelter, which connected to the

pad footing. Rafters and strut were added to transfer the load to the main support. Tensile strength were reinforced by adding bracing

between structure.

The main concern in designing the bus shelter is its accessibility. The bus shelter is designed to be highly accessible as users are able to approach and enter the shelter in all directions without any means of obstruction.

ACCESS 05

LOAD TEST ANALYSIS 06

Deformed double pitched roof prevents the accumulation of rainwater on itself.

Roofing struts are able to withstand the lateral load from rain and wind.

In this project, we had faced challenges especially during creating joineries which involve multiples connection. The problems were finally resolved after everyone in the group work together looking for solution through research.

After this project, we had learnt about:01 Apply the knowledge of skeletal construction and its joints to actual construction and design02 Analyzing the issues of strength, stiffness and stability of structure including modes of structural systems, forces, stress and strain and also law of static.03 Understanding of appreciate materials to suit the function of shelter.
