Investigations of past and recent earthquake damage have illustrated that the building structures are vulnerable to severe damage and/or collapse during moderate to strong ground motion. Among the possible structural damages‚ seismic induced pounding has been commonly observed in several earthquakes. A parametric study on buildings pounding response as well as proper seismic hazard mitigation practice for adjacent buildings is carried out. Three categories of recorded earthquake excitation are used for input

Kobe Earthquake An earthquake occurred on January 17th‚ 1995‚ at 5:46 am in the south-central part of Japan. This earthquake registered as 7.2 on the Richter scale and caused mass destruction. It was thus named The Great Hanshin Earthquake. It later earned the name as the Kobe Earthquake due to the amount of damage that Kobe‚ Japan suffered. Its focus was only 16 km below ground. Shock-waves splintered buildings‚ destroyed roads‚ and ruptured mains of gas‚ water‚ and electricity. Over 6‚400 people

this nightmare‚ was just beginning. All of a sudden‚ the ground began to shake as an earthquake rocked the Caribbean country. A estimated magnitude 7 earthquake had occurred and nearly 50 aftershocks followed. The quake was the most powerful experienced by the country in over two centuries‚ and it left 316‚000 people dead while forcing another million people to permanently evacuate from their homes (“Haiti Earthquake of 2010”). There is no doubt that along with the physical‚ tangible effects of this
