基于震害指数的预应力混凝土扁梁框架节点抗震性能评估
|
摘要
基于预应力混凝土扁梁框架节点拟静力实验研究结果,对国内外较常用评定结构抗震性能优劣的技术指标———粘滞阻尼系数、延性系数和震害指数进行了计算.根据计算结果,对3个评定指标进行比较和分析.首先分析了粘滞阻尼系数和延性系数的优缺点,随后介绍了震害指数在评定结构抗震性能的优越性,并在此基础上提出了震害指数研究的发展方向和建议.
Based on pseudo-static test results of joints of prestressed concrete flat-beam frame,the specifications on aseismic behavior inculding damping coefficient,ductility coefficient and seismic damage index are calculated.On the results of calculation,comparison and analysis are carried.At first,advantages and disadvantages of damping coefficient and ductility coefficient are introduced.At last,superiority of seismic damage index is introduced,and some suggestions for future research are brought forward.
