A structure's strength is derived from its shape and the materials it is constructed from. The strength of a structure is its capacity to withstand the forces that tend to break the structure or change its shape, according to PBS Learning Media. A triangle is considered the strongest structural shape. In the case of a triangular building, collapse occurs only due to material fatigue and not geometrical distortion.
