【摘要】 开孔钢板连接件是沿着作用力方向布置在混凝土和钢梁之间,依靠圆孔中形成的销钉状混凝土提供竖向和水平约束,具有很大的刚度、强度及其抗疲劳性能,更适合应用到荷载相对较大、对抗疲劳性要求较高的桥梁结构中.叙述了开孔钢板连接件的受力特点及其抗剪强度研究方面的进展,并介绍国外在桥梁结构中的几个应用实例.更多还原

【Abstract】 Perfobond shear connectors arrange along the force direction between the concrete slab and the steel beam.Concrete flows through the rib holes forming dowels that provide resistance both the vertical and hori- zontal directions.Because of its higher stiffness,strength and fatigue resistance performance,this connector is fit for the composite bridge with the great load and high fatigue resistance requirement.This paper describes the technique characteristics and the shear strength research progress of the new connector,and gives several applied instances of composite bridge in other countries.更多还原
