In a group of 6, we are required to select the design of the members in studio 3. In a group, we are to redesign the roof of the building by using truss design.

1. RADIAL TRUSS SYSTEM
BUILDING STRUCTURES 2 / PROJECT 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 TRUSS
A 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 TRUSS
The 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 TRUSS
The 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 TRUSS
A 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 RING
It is the innermost ring that
has four V-shaped columns
attached. This component
transfers load from the truss
system to the inner columns.
