摘要
考察无横隔板及有贯通横隔板加强的圆钢管混凝土结构梁柱节点的应变规律及强度计算法,对6个节点局部试件柱-钢梁翼缘节点进行试验,通过屈服线理论分析,讨论两种节点的应变规律并进行强度比较,最后提出节点抗拉全塑性强度和最大强度的计算方法,试验值与计算值较吻合。
It is focused on the systemic research of strain and local tensile strength of the connection between steel beam flange and concrete-filled circular tube column. Six specimens of beam-to-column connection and corresponding test method are introduced. The structure behavior and yield mechanism of connection are discussed, then estimation for local plastic and ultimate tensile strengths of connection using yield line theory is proposed.
