钢筋混凝土框架结构倒塌破坏能量分析的研究
|
摘要
本文采用能量时程分析法 ,将Q模型法引入框架结构的倒塌分析 ,通过对绝对能量方程和相对能量方程进行对比 ,推导出了相对能量方程中各项的数值表达式。利用双重破坏准则 ,确定了结构地震破损度标准 ,提出了建筑物倒塌破坏的评估理论与方法。最后对保证梁铰机制的构造措施进行了探讨
The step-by-step numerical integration for energy and the Q-model are used in the collapse analysis of reinforced concrete frame structure.An equivalent SDOF system for representing a MDOF system can be used in the step-by step numerical integration analysis.Based on the comparison between absolute energy formulation and relative energy formulation,the equation needed to calculate the various energy quantities of relative energy formulation is developed.Making use of the double control damage criterion and index,the evaluation theory and the collapse mechanism of the structure are put forward.At the end,the kinds of special joints,which are the efficient construction measure to strengthen the collapse-resistant ability of reinforced concrete frame structures are studied.
