| 摘 要： | 采用Penzien模型及Hertzdamp碰撞单元,建立了相邻结构考虑PSSI的碰撞模型,推导了其碰撞动力方程,并对相邻结构进行了碰撞模拟和参数分析.研究表明:虽然PSSI对结构本身的地震响应影响并不大,但对相邻结构的碰撞响应影响明显.同时,在一定范围内,防震缝宽度、碰撞刚度、结构周期比、桩的截面惯性矩以及土的剪切波速...

| Abstract: | Based on Penzien model and Hertz-damp collision element,the authors construct a collision model considering the PSSI effect and make a collision simulation and a parametric analysis for the adjacent buildings.The study results show that the PSSI effect has a significant influence on the collision between the adjacent buildings and the width of the seismic joint,the impact rigidity,the period ratio of the two adjacent buildings,the moment inertia of pile section and the shear wave velocity of the soil also h... |
