| Summary: | 碩士 === 國立臺北科技大學 === 土木與防災研究所 === 98 === This thesis investigates the results of shake table tests on six full-scale shear governed RC columns. Two types of RC columns were designed for the shake table tests. To evaluate the effect of the principal axis orientation on the seismic performance of RC short columns, in the three specimens of each type the principal axes of cross-section are in the directions of 0, 22.5 and 45 degrees to the excitation direction. The input ground motions are the acceleration time histories that recorded at the 921 Chi-Chi earthquake. The response time histories for the accelerations and displacements as well as the force-displacement hysteretic loops are presented in this study. The Strut-and-Tie Model was applied to the prediction of the shear strength and force-deformation relation of the tested RC columns. The calculated results compared with those obtained by shake table test show good agreement. Finally, the finite element analysis program SAP2000 with the Takeda and Pivot hysteretic model was adopted as the analysis tool for analyzing the non-linear behaviors of the tested RC columns.
