RADIAL TRUSS SYSTEMBUILDING STRUC TURES 2 / PROJEC T 1 / ROOF TRUSS

Circular planar trusses are proposed for the building as it reinforces the radial concept and is quick to pre-fabricate and install. The parallel chord truss is the main component of the truss system installed on the ground floor ceiling so that it supports the load of the first floor. Fabrication costs are greatly reduced as it is able to span the circular ceiling with a radial arrangement. Also, steel columns were installed to transfer load effectively from the truss to the ground.

Situated in Bukit Cina, its a hill that acts as a cemetery as well as a recreational park for people residing around it. Radiance is a Visitor Interpretive Centre that focuses on radiating the sense of familiarity and belonging of Bukit Cina towards the visitors. It has a courtyard at the center and above it a circular skylight allows natural light to permeate and connect with all the spaces on the ground floor.

1/ CIRCULAR TRUSSA load bearing component that adheres to the design of the building which has a circular skylight. The circular trusses span across the whole ceiling, receiving load directly from the first floor.

2/ U-SHAPED TRUSSThe U-shaped truss is a response towards the design of a unique staircase that connects the ground floor and the roof garden above. The truss bears the entire weight of the staircase and its users as the stairs hangs from it.

3/ WARREN BRIDGE TRUSSThe Warren bridge trusses are located around the circular planar trusses and the U-shaped truss. They act as mediators between the direct receivers of load and the columns as well as the load bearing walls.

4/ PLANAR TRUSSA minor component that merely acts as a capping point for the Warren bridge trusses. One of them also connects the circular truss system and the U-shaped truss system.

5/ INTERMEDIATE RINGIt is the innermost ring that has four V-shaped columns attached. This component transfers load from the truss system to the inner columns.
