As discussed earlier mentioned, concrete is quite strong in compression, but weak in stress. Greater earthquakes can make really big shear hundreds on structures. These shear hundreds matter the structure to both of those tensile and compressional masses. Concrete structures without reinforcement, like other unreinforced masonry buildings, can are unsuccessful https://cody7900d.blogtov.com/16308445/concrete-reinforced-with-rebar-can-be-fun-for-anyone
