菱形开洞软钢阻尼器及其在结构减震中的模拟分析
|
摘要
提出了菱形开洞加劲软钢阻尼器及其在整体结构中的数值模拟方法,并据此对菱形开洞软钢阻尼器的循环加载试验以及安装阻尼器的钢框架结构的震动台试验进行了模拟分析。验证了使用AN-SYS有限元程序进行数值模拟分析的可行性和准确性,同时证明了菱形开洞软钢阻尼器具有良好的滞回性能,在整体结构中能够达到较好的减震效果。
According to simulation analysis on hysteretic behavior and vibration suppression of the mild steel damper with the diamond-shaped opening and added damping and stiffness,the cyclic loading tests of the dampers and the shaking table test of a fame structure with installed the dampers are computed by the simnlation method.The practicability and accuracy of the simulation methods are proved well by using ANSYS program,and the superiorities of the hysteretic behavior and the vibration suppression of the damper in the overall structures are presented at the same time.
