摘要
对用于抗震加固的消能减震结构进行了弹塑性时程分析研究,主要解决以下几个问题:确定结构的振动模型;质量矩阵和阻尼矩阵的处理;确定结构或构件在反复荷载下的力-位移关系,或恢复力特性;附加阻尼矩阵及附加刚度矩阵;阻尼器的优化布置等.提出了简化优化设计法,针对加固工程,确定控制函数.最后给出了四层混凝土框架加固工程实例分析.
The elastic-plastic time history analysis on seismic retrofitting of the energy dissipation structures is researched,mainly solved following several problems: Definite structure vibration model;Definite quality matrix and damping matrix;Definite structure or the component force-displacement relation under the load repeatedly,or characteristic of restoring force;Attachment damping matrix and attachment stiffness matrix;Optimized dampers arrangement.The simplification optimization design method is proposed,in...
