摘要
鉴于当下对结构碰撞问题研究的紧迫性,采用地震工程仿真计算平台OpenSees软件,对主裙楼RC框架结构间的地震碰撞问题以及几种防震缝最小宽度确定方法进行研究,分析地震碰撞对主裙楼框架结构特性的影响以及影响主裙楼框架结构间地震碰撞效应的因素。通过比较现有相邻结构间地震碰撞问题的研究方法及特点,选取简化后的Hertz-damp碰撞模型(带间隙的非弹性杆单元模型)对主裙楼RC框架结构间的地震碰撞效应进行算例分析,并进行结构碰撞时程定量分析,具体研究了质量比和间隙比对主裙楼RC框架结构间碰撞效应的影响以及OpenSees软件对该类碰撞问题研究的适用性。
A study on the collision problems between the main-podium RC frame structures is carried out,and several kinds of methods to determine the minimum width for the further fundamental research are developed by using the earthquake engineering simulation platform OpenSees software. The characteristics of the collision on the main-podium RC frame structure and the factors that affect the collision between the main-podium RC frameworks are also investigated. By comparing the research methods and characteristics of the collision between the main-podium frame structures,the simplified Hertz-damp collision model（ with clearance of elastic rod element model） is selected to study the main-podium RC frame structure of pounding effect for example analysis,and the quantitative analysis of structural pounding is conducted. The pounding effect of mass ratio and the clearance ratio between the main podium RC frame structure is studied as well as the applicability of OpenSees to such kind of pounding research.
