The building frame is akin to the legs of a table, providing necessary support. Once the frame is damaged, the building can collapse, similar to option A) how a table collapses without its legs. A wrecking ball causes a wall to fall by rotating at the base when struck near the top.
Destroying the building frame is like kicking the legs out from under a table because the frame of a building, much like the legs of a table, provides the structural support necessary to hold the building up. Once the frame is compromised or destroyed, the building loses its support and can collapse. This analogy helps to understand the importance of the building frame in construction and demolition processes. For example, during a controlled demolition, if the frame of a building is targeted or weakened, this can lead to the collapse of the entire structure, similar to how a table would collapse if its legs were kicked out. Additionally, when the wrecking ball strikes a tall concrete wall near its top, the wall is likely to fall over by rotating at its base, due to the leverage effect of hitting a high point on the structure.
