Shaking table tests on wooden structure of Liaocheng Guangyue Tower
摘要
Abstract
To investigate the dynamic response and seismic performance of a hybrid timber pavilion structure that combines both through-columns and stacked columns under earthquake motions,shaking table tests were performed on a simplified model of the Liaocheng Guangyue Tower with a scale ratio of 1/4.5.El Centro waves,Taft waves,and artificial waves were selected as seismic excitations,and the failure modes,dynamic characteristics,acceleration responses,displacement responses and strain responses of the model under different seismic intensity levels were obtained.The results indicate that the model damage primarily concentrated on slight pull-out of the mortise-tenon joints,mild cracking of the Ludous,and partial outward inclination of partial upper sill.The first and second natural frequencies of the structure decreased by 22.8％and 7.8％,respectively,while the corresponding damping ratios increased by 59.3％and 18.7％.The acceleration amplification coefficients for each floor of the structure ranged between 0.40 and 1.0,and decreased with increasing seismic excitation intensity.The maximum story drift angle of the structure was 1/29 under the excitation of rarely occurring 7-degree earthquake,with no significant tilting damage observed,indicating good deformation capacity of the structure.关键词
