摘　　要：对4种夹芯复合材料/钢板连接接头进行四点弯曲试验和数值研究。试验获得了接头的失效载荷、载荷-位移曲线以及失效模式,通过对比发现接头的承载能力与接头形式有很大关系。采用有限元方法获取了接头载荷-位移曲线以及应力分布,并研究了接头各设计参数对接头弯曲刚度的影响。Four different types of composite-to-steel joints were experimentally and numerically investigated under moment.The failure loads,load-deflection cures and failure modes were then obtained and compared with each other.Test results show that the ultimate load or joint load-carrying capacity appears to be very sensitive to the joint configurations.The stress distributions and the load-deflection cures were numerically investigated by finite element methods for the various joint parameters.
