As talked about above, concrete is extremely solid in compression, but weak in pressure. Larger earthquakes can make extremely massive shear masses on constructions. These shear masses subject matter the composition to equally tensile and compressional hundreds. Concrete buildings without reinforcement, like other unreinforced masonry buildings, can fall short through https://construction-engineering25677.shotblogs.com/an-unbiased-view-of-concrete-reinforced-retaining-wall-49756432
