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.

关 键 词:抗震加固  消能减震  优化设计  控制函数

Abstract: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 view of the seismic retrofitting project,the control function on the seismic retrofitting structure is determined.An example about seismic retrofitting analysis of four-floor reinforced concrete frames is given.
Keywords:seismic retrofitting  energy dissipation  optimization design  control function
