Constructions employing Portland cement concrete generally consist of metal reinforcement due to the fact this sort of concrete might be formulated with higher compressive toughness, but generally has lessen tensile power.

As discussed above, concrete is very potent in compression, but weak in pressure. Larger earthquakes can generate incredibly substantial shear loads on constructions. These shear hundreds topic the construction to equally tensile and compressional loads. Concrete constructions without reinforcement, like other unreinforced masonry structures, can fall short throughout critical earthquake shaking.
