As mentioned earlier mentioned, concrete is extremely strong in compression, but weak in stress. More substantial earthquakes can produce really substantial shear hundreds on structures. These shear masses issue the structure to both equally tensile and compressional loads. Concrete constructions without reinforcement, like other unreinforced masonry buildings, can fall short through severe earthquake shaking.
The towers had been made working with reinforced concrete, which authorized with the one of a kind curved forms and cantilevered balconies that define the developing's physical appearance.
