机器激励下考虑填充墙影响的结构动力响应分析
|
摘要
为了研究在机器激励下填充墙对结构动力响应的影响,根据现场实测结果,从时域上利用Newmak法对该结构进行动力时程分析;基于实测数据的功率谱,拟合出Kanai-Tajimi模型的参数,利用SAP2000的PSD分析模块对结构进行随机振动分析,与未考虑填充墙影响时结构的动力响应进行分析比较。研究结果表明:考虑填充墙影响后,结构的自振频率增大,与实测结构频率及机器工作频率更接近;考虑填充墙影响后,结构的加速度、速度以及内力响应均增大,位移响应因结构的共振效应也增大。
The dynamic response analysis of infilled shear wall structure under machine excitation was studied.Based on the tested results,the dynamic time history analysis using Newmark method was applied.Based on the power spectrum density(PSD) of tesed data,parameters of Kanai-Tajimi modal were fitted.Using the PSD analysis of SAP2000,the random vinration analysis was carried out,and the response results were compared to those of the structure without infill wall.The results show that the natural frequency of infilled shear wall structure increases,and is close to the tested frequency and machines' working frequency.The acceleration,velocity,displacement and internal force responses all increase.
