A Review Article On The Performance Based Seismic Design Of Structures, Reem Hatem Ahmed, Sahar Elaiwi, Shelan Hameed Ameen

Al-Esraa University College Journal for Engineering Sciences

For the most part, seismic design builds complex structural systems using the same small number of essential structural components as non-seismic design projects. Based on the building regulations, structures are frequently designed to "withstand" the largest earthquake with a given likelihood that is projected to happen at their location. This means that by avoiding structures from collapsing, the number of fatalities must be maintained to a minimal. Seismic design involves knowing the many failure modes regarding a structure and giving it the right stiffness, strength, ductility, and layout for ensuring that these modes do not take place. In this essay, …
