【摘要】 探讨具有水平连接刚度突变特征的钢筋混凝土结构的一般力学特点与动力反应分析方法。以莆田市广播电视中心工程结构为例 ,揭示结构因水平连接刚度突变而导致的复杂振型、地震作用下局部动应力集中等特点。通过有限元法模拟了水平连接刚度突变处不同的连接方案对结构动力特性与地震反应的影响更多还原

【Abstract】 General mechanic differences and methods of dynamic response analysis of RC structure characterized by abrupt change in horizontal connection stiffness are discussed. For structure of Putian Center of Radio, Film and TV, complicated modals and stress concentration resulted from abrupt change in horizontal connection stiffness are revealed by FEM.Different connective plans located in place of abrupt change in horizontal connection stiffness have effects on structural dynamic properties and seismic response.更多还原
