竖向地震若干问题研究
|
摘要
地震是一种严重的自然灾害。目前的工程抗震研究中,水平地震的研究已经形成了比较完善的理论体系和计算方法。然而大量研究和震害表明竖向地震对结构的影响不容忽视。详细总结并分析近几十年来各种类型结构在竖向地震作用下的震害和原因,阐述竖向地震作用的计算方法、结构竖向动力特性和竖向与水平向加速度峰值比(V/H)的关系。简要介绍竖向减震隔震技术的应用与发展。研究结果表明,竖向地震的计算方法亟待完善,《建筑抗震设计规范》(GB50011-2001)对竖向加速度反应谱的取值过于简化,应用竖向隔震减震装置可以显著降低结构在竖向地震下的反应。
Earthquake is one of the most serious natural disaster in the world,it has made great loss to our human beings.The research of the horizontal earthquake-resistant theory and design methods has perfected in recently.However,the theoretical study and a large number of the phenomenon of earthquake disaster show that we could not ignore the vertical earthquake excitation to structures.The article summarizes and analysis some structure's damage due to vertical earthquake;Discussing the calculation methods,vertical dynamic characteristic and the relationship between the peak value of vertical acceleration and the horizontal acceleration.The application and progress in the field of vertical isolation is induced at last.The result shows that the vertical acceleration response spectrum recommend by code is too simplied and the calculation methods need perfected;Vertical isolation equipment can reduce the reaction of structures under vertical earthquake obviously.
