【摘要】 通过对某超限高层钢筋混凝土工业框架结构进行小震、中震、大震下的弹性及弹塑性分析研究,得出了既有建筑物现阶段的实际抗震性能,并在此基础上尝试采用了目前国际上较先进的基于抗震性能目标的性能抗震设计理论,对既有建筑物抗震加固设计提供了不同性能目标下的不同加固方案,并且对各个方案逐一进行分析对比,最终确定一种安全、适度、适用、可实施性强、经济合理的加固方案进行抗震加固设计。更多还原

【Abstract】 Through the elastic and elastic and plastic analysis and research for the over limit tall industrial frame structure under the moderate earthquake and intense earthquake function,we get a conclusion in the practical aseismatic capability of old frame,and regard this as the foundation,we try to adopt the most advanced theory of the capability of the aseismatic design based on object of the aseismatic capability,and provide different reinforce methods for some different object of the aseismatic capability,and analyse and contrast in these different methods,at last,select a secure and moderate and appropriate and implementary and economical method of the aseismatic reinforce.更多还原
