What is keeping this structure in equilibrium?
Why are structures often made up of multiple interconnected components?
A designer labels a structure as “frame” rather than “solid.” What type of classification is this?
A design consultancy is developing three types of public-use structures. These include a cantilevered balcony system, a modular pedestrian bridge, and a public art canopy. Each design prioritizes different structural principles for stability, safety, and aesthetics.
Figure 1 shows a cantilevered steel balcony protruding from a modern building façade.
Identify one structural force acting on the cantilevered balcony.
Explain one way in which cantilevers resist the force identified in part 1.
Figure 2 shows a temporary modular pedestrian bridge made from prefabricated trusses.
Explain one advantage of using a truss structure for the modular bridge.
Describe how the shape of a truss provides rigidity.
Figure 3 shows a large public canopy made from a grid shell structure supported by tension cables.
Outline two reasons why tension members are suitable for the canopy.
Compare the structural behavior of the grid shell canopy with a rigid frame structure in public architecture.
