钢混组合梁连接件,主要是用以承受钢筋混凝土翼板与钢梁之间的纵向剪力的,严格地说,它同时还起抵抗翼板与钢梁之间的掀起作用。国外经过二、三十年来的试验研究和工程应用,对组合梁连接件的工作性态已有了实质性的认识。五十年代,在桥梁中连接件主要是采用螺旋筋和弯筋构成,后来逐渐被槽钢及栓钉所代替。现在,无论在桥梁上还是在房屋结构中,栓钉连接件已普遍为各国所采用。
The steel-concrete composite beam connector is mainly used to withstand the longitudinal shear force between the reinforced concrete wing plate and the steel beam. Strictly speaking, it also plays a role in resisting the lift between the wing plate and the steel beam. After 20 years of experimental research and engineering application in foreign countries, there has been a substantial understanding of the working behavior of composite beam connectors. In the fifties, the connecting parts in the bridge were mainly composed of spiral ribs and bent ribs, which were gradually replaced by channel steel and studs. Nowadays, stud connectors have been widely adopted by countries, both on bridges and in housing structures.
