As discussed over, concrete is extremely strong in compression, but weak in stress. Larger earthquakes can deliver quite large shear masses on buildings. These shear masses subject the composition to equally tensile and compressional hundreds. Concrete structures without reinforcement, like other unreinforced masonry constructions, can are unsuccessful throughout intense earthquake https://tornadosocial.com/story5339966/the-best-side-of-concrete-reinforced-beam
