As reviewed over, concrete is extremely robust in compression, but weak in stress. Larger earthquakes can deliver very significant shear loads on constructions. These shear loads matter the composition to both tensile and compressional masses. Concrete buildings without reinforcement, like other unreinforced masonry constructions, can fail during extreme earthquake shaking. https://cocoagriculture05936.free-blogz.com/83028672/little-known-facts-about-concrete-reinforced-stone
