混合梁结合部受力研究

混合梁是钢梁与混凝土梁,在梁体纵向通过连接件、承压板、预应力筋或锚杆等结合在一起而形成的结构。近年来,混合梁得到广泛应用,结合部的受力特性研究,更显得尤为重要。通过实际工程的结构设计,并总结一些规律对今后的设计具有一定的指导作用。

Study on Stress at Combination of Composite Girder

The composite girder is a structure of steel girder and concrete girder combined by connector,bearing plate,pre-stressed bar or bolt at the longitudinal direction of girder.In recent years,the composite girder is widely used.The study on the stress character of its combination is especially important.According to the structural design of practical cases,the article sums up some rules able to be referred for the future designs.
