摘要:
以“5·12”汶川地震灾区典型教学楼框架为对象,研究了框架与楼梯的共同工作性能,包括框架独立单元的静力抗侧刚度、整体框架的静力抗侧刚度、整体框架动力特性,并进行了地震反应谱分析以及地震时程分析。结果表明:楼梯的存在对框架抗侧刚度、动力特性、规范地震反应谱下内力峰值、不同地震作用下的构件内力及节点反应谱峰值均存在较大的影响。所得结论可为灾区类似建筑的新建和修复加固提供必要参考。
Abstract:
Associating with the typical teaching building in “5·12” Wenchuan Earthquake disaster area of Sichuan Province, the interaction performance between frames and stairs was explored. The interests cover the static lateral stiffness of the static single frame unit, the lateral stiffness of the whole frame, the dynamic performance of the whole frame, the responding analysis under the standard earthquake spectrum of current Chinese code, and the calculation of time history under different earthquake records. The results show that the existence of stairs greatly affect the lateral stiffness of frame, dynamic performance, the peak of internal forces under standard earthquake spectrum of current Chinese code, and the peak of internal forces and node response spectrum under different earthquakes. These can be used as necessary references for the construction and strengthening of the similar buildings in disaster area.
