Analytical simulation of shake-table responses of a 1: 5 Scale 9-Story RC piloti-type residential building model

This paper presents the results of analytical simulation of shake-table responses of a 1: 5 scale 9-story RC piloti-type residential building model having a torsional eccentricity at the ground story by using the PERFORM-3D program. Through the comparison of experimental and analytical results, the reliability and limitations of the analysis are evaluated. Based on the observation of correlation between experiment and analysis, the following conclusions are made; (1) In the analytical results under the design earthquake and the maximum considered earthquake in Korea, global behaviors reveal that the base shear, roof drift, and the overturning moment are closely simulated, though torsional moment and deformation are almost 50% of those of the experiment in amount. (2) Since the lateral resistance of the Y directional exterior frame having infilled walls in the analytical model could not be simulated, the contribution of torsional moment by the stiff side with infill wall underestimates that of the experiment.
