RULES OF ELASTOPLASTIC DRIFT DECOMPOSITION OF RC FRAMES AND THE TARGET DRIFT OF MEMBERS

  • 摘要: 研究了RC框架在弹塑性状态下层间位移与构件变形之间的关系。引入塑性变形分布因子作为参数,建立了框架节的塑性变形分布因子与位移延性系数、强柱系数之间的关系,即χ-μδc关系;在此基础上,提出了RC框架弹塑性位移的解构规则,可用于求解构件的目标侧移角,从而实现了基于位移设计的关键一步。
    Abstract: Relations between the elastoplastic inter-story drift of frame and the deformation of members are studied. Introducing the plastic deformation distribution factor χ as a parameter, the relations among χ, displacement ductility ratio μδ and column overstrength factor ηc, namely χ-μδc equations, are presented. Furthermore, the rules of drift decomposition are developed. By decomposing the drift demand, the target deformability of beams and columns are determined, which is a key step of the displacement-based design.
