罕遇地震作用下考虑接触效应的高层建筑上部结构-桩-土体相互作用的非线性分析
|
摘要
为更好地研究和预测高层建筑结构在地震尤其是罕遇地震作用下的地震响应,选取经历汶川地震的四川绵竹高层建筑剑南春大酒店为研究对象,利用大型有限元软件ABAQUS建立上部结构-桩-土体三维实体模型,对比结构在刚性地基条件下与土地基条件下的自振特性及上部结构动力响应的区别,得出桩间土体和桩端土体对上部结构动力特性的影响规律,同时考察上部结构非线性、土体非线性和桩-土接触非线性对相互作用体系非线性反应的影响。动力弹塑性时程分析结果与已有震后调查资料对比表明,考虑相互作用效应的高层建筑上部结构抗倒塌能力比传统设计方法更符合实际。本文方法具有很强的实用性,结合大型有限元软件ABAQUS可以较准确分析计算高层建筑上部结构-桩-土体相互作用的强非线性问题,为工程实践提供重要的理论依据。
In order to study and predict nonlinear seismic response of high-rise buildings better under earthquake especially severe earthquake,the Jiannanchun hotel,located in Mianzhu city of Sichuan province,which endured Wenchuan Earthquake,is selected for research object.Superstructure-pile-soil mass three-dimensional finite element physical model is established by the popular finite element software ABAQUS.Different dynamic characteristics of superstructure caused by varied inter-pile soil and bearing layer soil are discussed via comparing the vibration characteristics and dynamic responses of superstructure upon rigid subgrades and pile-soil foundation.Conclusion is drawn for the influences of inter-pile soil and bearing layer soil on dynamic characteristics of superstructure thereby.Meanwhile,the influences of nonlinearities of superstructure,soil mass and pile-soil contact on nonlinear responses of the interaction system are considered.Comparison between time-history analysis results of dynamic elastoplasticity and disaster investigation performed after Wenchuan Earthquake indicates that the ability of anti-collapse of superstructure of high-rise buildings considering interaction effect meets the actual circumstances better than traditional design method.Results of finite element model matching site investigation well show that software ABAQUS is greatly applicable for severe nonlinear interaction problem analysis of high-rise buildings;and it can be guidance for engineering practice.Besides,the proposed method supplies important theoretical basis for engineering practice.
