【摘要】 本文通过在钢结构模型各层均设置相同数量的软钢阻尼器,采用质点系模型和自编的时程分析法程序,讨论了不同消能减震体系之间各个响应值在两条人工波下的减震效果,研究了输入能、塑性能与输入地震波和阻尼器数量之间的关系。结果表明,层间最大角位移的减震效果随着阻尼器数量的增加而明显,层间最大剪力的减震效果依赖于输入地震波。更多还原

【Abstract】 In this paper,the same numbers of mild steel dampers were set in every storey of steel frame model. Base on the mass-system model,time-history analysis program was employed to discuss the damping effectiveness of different response values under two seismic waves,and the relationship between input energy、 plastic energy and seismic waves、numbers of dampers were also studied.The results indicate that the damping effectiveness of the maximal interlaminar displacement angle is more obvious as the numbers of dampers increasing,and the damping effectiveness of the maximal interlaminar shearing force depends on the input seismic waves.更多还原
