摘　　要：钢-高强混凝土组合梁抗弯承载力对组合梁的结构设计很关键,组合钢梁上翼缘受混凝土楼板约束,其承载力必然受到一定的限制,此外,在连续组合梁的负弯矩区,随着荷载不断增加,整个结构就会在负弯矩区会发生破坏。为了避免这种破坏的产生,利用通用有限元程序SAP2000对钢-高强混凝土组合梁进行了抗弯承载力分析,研究其抗弯承载力的影响因素,有利于确保钢-高强混凝土组合梁的安全性。It is very important to analysis of the flexural bearing capacity of the steel-high strength concrete composite beams, but the combination on the flange of steel beam and their bearing capacity is limited by certain inevitably, in addition, in the negative bending regions of continuous composite beams, with the constant increase of load, the process of the whole structure will damage will happen in the negative moment region, in order to avoid the damage, we must use general finite element program SAP2000 to analyze of bearing capacity of the steel and high strength concrete composite beams, further the influence factors of bearing capacity,and ensure the safety o four engineering performance, in favor of the engineering structure.
