摘要
钢-混凝土组合梁中剪力连接件的主要作用是为了抵抗钢和混凝土之间的滑移和分离。PBL剪力键是近年来出现的一种新型剪力连接件,国内外虽然对PBL剪力键做了一些研究并取得一定的成果,但是对PBL键的形式、尺寸和相应的承载能力还未作出规定;尤其是对翼缘折形开孔板剪力连接件的力学性能尚未进行研究。试验小梁试件的剪力连接件采用翼缘折形开孔板剪力连接件,通过对波折钢腹板小梁的荷载加载试验来研究该剪力连接件的力学性能。
The main function of the shear connectors of steel-concrete composite beam is to resist slippage and separation between the steel and concrete.PBL shear key is a new type of shear connectors in recent years.Although PBL shear keys have done some research and have made certain achievements at home and abroad.It has not yet provided for the form of PBL key,size,and the corresponding carrying capacity.Especially the flange-shaped plate with a hole off the performance of shear connectors have not study yet.The test specimens of orbicular shear connectors is about fold-shaped plate with a hole flange shear connectors.The mechanical shear connector performance through the twists and turns of the load of steel web orbicular load tests is studied.
