SPEAR (Seismic Performance Assessment and Rehabilitation of Existing Buildings) INTERNATIONAL WORKSHOP

The seismic evaluation and the retrofit design of existing buildings due to seismic loads is a very important problem of most of the earthquake prone countries. In this paper, existing four and seven story RC buildings are evaluated according to the 1998 Earthquake Code of Turkey and found to be weak and strengthened by adding shear walls and/or jacketing some columns, then results have been tested using ATC– 40 guidelines and the capacity spectrum method. Moreover, in order to see the effect of near fault earthquakes, a nonlinear time history analysis has been carried out for seven story building using five ground motions of recent earthquakes in Turkey. As a conclusion, the buildings strengthened according to the code are over-designed and the near fault effects have to be introduced to the existing Turkish Earthquake Code.
