In view of the recent earthquake damage caused by the 921 Chi-Chi Earthquake and the 2016 Meinong Earthquake reinforced concrete structures in Taiwan are vulnerable to eccentric and irregular torsional damage Therefore experts and scholars are devoted to the analysis and simulation of the collapse resistance of the structures with torsional irregularity and a series of half-scale seven-story reinforced concrete structures with different sources of irregularities were tested on the shake-table at the National Earthquake Engineering Research Center (NCREE) Tainan laboratory It is expected that the nonlinear torsional response of the reinforced concrete structures can be experimentally studied This study aims to research the nonlinear torsional behavior of existing reinforced concrete buildings under seismic motion through the shake-table tests performed by NCREE and emphasize the characteristics of the weak first-story system and use the finite element software “ABAQUS” for dynamic analysis which discusses in detail how to establish an appropriate analysis model to effectively simulate its stiffness plastic behavior of concrete failure mode and nonlinear torsional response Finally the dynamic behavior and related data obtained by simulation are compared with the experimental data measured by NCREE to discuss the accuracy of the analysis technology for nonlinear torsion and draw conclusions and future suggestions
