WebApr 28, 2013 · Wind Effects on Structures Wind effects on structures can be classified as ‘Static’ and ‘Dynamic’. Static- Static wind effect primarily causes elastic bending and twisting of structure. Dynamic For … WebStructures I: Lateral Loads. Lateral Loads. Most lateral loads are live loads whose main component is a horizontal force acting on the structure. Typical lateral loads would be a wind load against a facade, an earthquake, the earth pressure against a beach front retaining wall or the earth pressure against a basement wall.
