摘　　要：以高性能钢HPS485W、HPS690W及高强混凝土C60、C70为主要研究材料,对高性能钢-高强混凝土组合梁进行弹性和塑性分析;通过简支组合梁的实例,分别计算各组不同截面不同材料组合梁的屈服弯矩和极限弯矩,发现高性能钢-高强混凝土组合梁的抗弯承载力比普通组合梁大大提高;另外运用有限元软件ANSYS模拟上述实例中的各组组合梁,并将有限元数值模拟结果与理论计算结果相比较,以验证其正确性和合理性。In this paper,HPS 485W,HPS 690W and HSC60,C70 are taken as the main materials,and the elastic and plastic analysis of the HPS（high performance steel）-HSC（high strength concrete） composite beams is introduced.Then according to some examples,the yield and ultimate moments are calculated in the different cross-sections and different materials of composite beams.The result shows the flexural capacity of HPS-HSC composite beam is much larger than the concrete composite beam＇s.In addition,using finite element program ANSYS to simulate the composite beams of the above examples,the results of finite element numerical and the theoretical results are comprised,and they can be verified each other.
