Abstract
One of the major natural calamities is earth quake, which come arise due to ground shakes. The variations of earthquake forces are random and have different intensity from place to place. Low rise buildings easily withstand against these accelerations as compared to high rise buildings which are succumbed to damage more rigorously. The Western region of Saudi Arabia lies in low to moderate seismicity regions. Majority of the structures built are seismically active & are designed primarily for combination of gravity and wind loads with no consideration of seismic loading. The areas near the holy city of Madinah city recorded seismic events of magnitude 5.7 in 2009. Therefore the performance based analysis of buildings are required to understand the seismic performances. The seismic design of masonry in- filled RC frame buildings is handled in different ways across the world.
