THE DYNAMIC ANALYSIS OF FINITE ELEMENT OF FRICTION-DAMPED SHEAR WALL
-
摘要: 用有限元法编制了结构动力反应分析程序,比较了加与不加阻尼器两种开缝剪力墙之间的动力反应差异。结果表明,摩擦阻尼式剪力墙在延性、耗能及动力反应上都明显好于其他形式的剪力墙,这种剪力墙体系为结构抗震作了第二道防线,使得结构在地震中将损害减至最小。Abstract: With finite element method, time- history dynamic analysis has been used to study and to demonstrate how much effect the concrete shear wall with friction- damped joints does compared with that without friction- damped joints during seism. It has been improved that when the joints slip, they soften the otherwise rigid wall and educe the seismic response, so it enhances the ductility and the ability of energy dissipation.
