WEEK 5 COLUMNS, GRIDS AND WALL SYSTEMS ACTIVITY: Oval Pavilion Model Making Activity Task: Making a 1:20 scale model of Oval Pavilion by analyzing the architectural and structural drawings. Our group’s work is to build the right hand side of the steel canopy truss (section 5-7 as seen on Grid D Spine Truss Elevation on S04.01). The canopy truss is made of steel because steel is very strong, rigid and durable. For this model, we chose balsa wood as material.
Grid D Spine Truss Elevation
Firstly, the main frame system was made. The top and bottom cords are the parallel beams that run the length of the truss. The two beams are connected by web members. The web members form triangles because this structure can disperse the load of the beam and prevent deformation of beam.
The vertical element provides extra support for the
entire system.

Secondly, we made the cantilevers which extend from the main frame. It to help support the roof cladding. This added reinforcement is also a triangle because the triangle is more stable.
The end of the canopy can transfer the load
to
the
ground.
The
two
cantilevers of this part is not in a straight line like section 5 and 6. It is benefit to disperse the load of roof. the vertical column support the whole frame and transfer the load to the ground. Finally, a brace was added. It prevents movement of the cantilevers that makes the structure more stable

Glossary Stud: a timber member in construction usually for connection two sides. Axial load: a force administered along the lines of an axis. Nogging: an architectural term used for the filling in-between wall framing in buildings. Buckling: is characterized by a sudden failure of a structural member subjected to high compressive stress. Lintel: a load-bearing building component. Seasoned timber: timber with a moisture <15%
