采用滚动隔震的两种结构考虑土-结构相互作用影响研究
|
摘要
针对高烈度区采用滚动隔震的框架结构及框剪结构,研究考虑土-结构相互作用对于结构性能的影响,运用ANSYS有限元分析软件建立结构三维有限元模型,研究对比了不同场地类别下两种结构体系的动力特性及地震响应。结果表明,滚动隔震能有效降低结构的反应。在考虑土-结构相互作用后,两种结构体系自振周期、结构位移等都有一定的增大,框剪结构受到的影响更大。抗震分析时需要考虑土-结构相互作用的影响。
Using rolling isolation in high intensity area,the influence of soil-structure interaction on structure performance of frame and frame shear structure is studied. 3D model is set up by ANSYS. The dynamic characteristics and seismic response of two kinds of structure systems under different site soil are analyzed. The results show that the rolling isolation can effectively reduce the structural response. After considering soil-structure interaction,the natural vibration period and the displacement of two kinds of structure systems has certain increase,and the influence of frame shear structure is larger. So the influence of the soil-structure interaction should be considered in seismic analysis.
