摘要
分析方、矩形钢管混凝土柱子在轴压和双向弯矩作用下形成塑性铰时轴力-双向弯矩之间的相关关系。采用自编软件计算方钢管和矩形钢管混凝土截面,提出了简化计算式计算方、矩钢管混凝土截面的承载力。同时对圆钢管混凝土也进行了推导,发现矩形钢管混凝土单向压弯的计算式也适用于圆钢管混凝土柱子。
This paper presented an analysis of the interactive relations between axial forces and biaxial bending moments at the state of plastic hinges. A simplified method was proposed to determine the interactive surfaces by a self-compiled simple computer program. Examples were presented for square and rectangular boxes filled with concrete, and simplified equations were proposed to calculate their sectional load-carrying capacity. For circular pipe filled with concrete, derivation was carried out and it was found that the equations proposed for rectangular box were also applicable for circular CFT columns.
