his paper addresses the behavior of multistorey structures considering soil structure interaction under
earthquake excitation. For this purpose, sample 3, 6, 9 storey RC frames are designed based on Turkish Seismic
Design Code and analyzed in time domain with incremental dynamic analysis. Strength reduction factors are
investigated for generated sample plane frames for 64 different earthquake motions recorded on different site
conditions such as rock, stiff soil, soft soil and very soft soil. According to the analysis result, strength reduction
factors of sample buildings considering soil structure interaction are found to be almost always smaller than
design strength reduction factors given in current seismic design codes, which cause an unsafe design and nonconservative
design forces.
