Most mid-rise and high-rise buildings in the earthquake-affected regions were constructed with seismic-force-resisting systems consisting of reinforced concrete structural walls. Similar construction is also prevalent in regions of high seismicity in the

In 2007, the National Institute of Standards and Technology (NIST) awarded a National Earthquake Hazards Reduction Program (NEHRP) "Earthquake Structural and Engineering Research" contract (SB1341-07-CQ-0019) to the NEHRP Consultants Joint Venture, a
Seismic fragility represents the probability that the structural response exceeds a given performance limit state due to a specified intensity of ground motion, and it has a direct relationship with the cost of rehabilitating the structural system. In this
