摘要
考虑结构的材料非线性、几何非线性、节点区锚固钢筋的滑移和节点刚域等因素的影响,采用5区段变刚度法,编制了钢筋混凝土框架分析程序。该程序可对多层多跨框架进行非线性分析,且通过与试验结果对比吻合较好,从而为研究钢筋混凝土框架的非线性设计提供了理论分析手段。
An analysis program of reinforced concrete frame is workout by use model of variety of stiffness divided into five parts while the influence of material non-linear,geometry non-linear,sllp of anchor reinforcing bar and rigidity section of node to reinforced concrete frame is took into account in this paper. The calculatod results coincide precisely with the practical measurements.
