Comparison between Analyzing and Testing of Structures under Ground Movements

Abstract

This study performs time history analyses of 4-storey plane building model under base movements with 2 approaches i.e.,acceleration and displacement approaches. Results of the analysis show in form of acceleration history at each building level. Thisstudy also performs the shaking table test to verify the analytical results. The building model is testing under 4 different frequencies harmonic movements i.e., 1.0 Hz, 2.0 Hz, 3.0 Hz and 4.0 Hz. Experimental results in form of acceleration history at each level are
compared with the analytical results. The comparisons show that the acceleration approach gives higher maximum accelerationthan those from experiment. While, the displacement approach gives more accurate results.
