基于SIMULINK不规则建筑AMTMD抗震控制的模拟
|
摘要
研究了地震作用下ATMD和AMTMD控制不规则建筑的行为,以在时域内进一步验证ATMD和AMTMD的有效性和鲁棒性。建立了不规则建筑-ATMD和AMTMD系统的SIMULINK仿真分析模型,考虑结构刚度的确定性和不确定性,并使用实际的地震记录,在时域内,进行地震作用下不规则建筑-ATMD和AMTMD系统的SIMULINK仿真分析。通过分析两种控制装置的有效性和鲁棒性,比较了两种控制装置的优劣。通过大量的计算与比较综合出结论,为不规则建筑的地震振动控制设计与实现提供了参考。
Simulations of earthquake-resistant performance of asymmetric buildings with active tuned mass dampers (ATMD) and active multiple tuned mass dampers (AMTMD) are presented here, so as to further validate the effectiveness and robustness of ATMD and AMTMD in reducing both the translational and torsional responses of asymmetric buildings in time-domain. Taking into account both the certainty and uncertainty in the structural stiffness, SIMULINK analysis is implemented to a three-floor asymmetric steel structure building model with ATMD and AMTMD subjected to various earthquakes. Through simulation and comparison, some useful conclusions are obtained for earthquake-resistant control designs and implementation of asymmetric buildings subjected to earthquakes.
