某幼儿园框架结构粘滞阻尼器减震分析

摘要

Combined with the cases of four-storey reinforced concrete frame structure of a kindergarten in Kunming City,the software ETABS was adopted for energy dissipation analysis of the kindergarten.The viscous dampers was simulated with additional nonlinear damping units in this paper.The results show that the structural layer shear,and interlayer displacement angle have been reduced obviously than before strengthening for more severe earthquake.The largest interlayer displacement angle can significantly reduce for larger earthquake.The both displacement angle can satisfy the requirements of specification.%结合昆明市某幼儿园四层钢筋混凝土框架结构的工程实例,采用ETABS对该幼儿园进行消能减震分析,用附加非线性阻尼单元模拟粘滞阻尼器.结果表明,多遇地震时,结构层剪力、层间位移角较未加阻尼器前有显著减小;大震时,层间最大位移角也能显著减小;两种情况下的位移角均满足规范要求.
