| 摘 要： | 本文采用能反映基础与地基间接触面力学特性的弹塑性薄层有限连接单元与二维有限元相结合的方法,探讨了高层建筑在爆炸空气波作用下的动力反应,着重研究了基础与地基间产生的滑移与翘离效应。还探讨了有限元边界条件,结沟、基础与地基材料等因素对结构的动力反应、基础与地基间的滑移与翘离效应的影响。

| Abstract: | In this paper the dynamic response of a high-rise building under explosive impulsive loading is studied by two-dimensional finite element method combining with elasto-plastic thin layer joint element, by which the mechanical characteristics of the contact surface between soil and the foundation can be described. Special attention is paid on the sliding and uplift of the foundation from soil. The influence of the boundary conditions of the finite element method,materials of the structure.the foundation and soil upon the response of the structure,sliding and uplift of the foundation are discussed. |
