组合楼盖中钢与混凝土之间的剪力传递是通过设置在钢与混凝土之间的剪力连接件实现的。开孔板式抗剪件具有抗剪承载力大、抗疲劳性能好、施工简单的特点。根据剪力传递的方式设计出适用于建筑领域的开孔板式抗剪件。采用静力推出试验方法,通过11个模型试验,研究分析出该种抗剪板的破坏形态以及抗剪钢板厚度、高度、开孔直径、孔内钢筋直径、穿孔钢筋的有无等因素对抗剪板抗剪承载能力和抗滑移特征的影响。结果表明:该种抗剪件具有良好的力学性和经济性,特别是在开孔中穿钢筋时,可大幅度提高试件的抗剪承载力和延性性能。
Shear transfer between the steel and the concrete in the composite floor is achieved by a shear connection between the steel and the concrete. Open-plate shear with shear capacity, anti-fatigue performance, the construction of simple features. According to the way of shear transmission design for the construction field of open-hole plate shear. Static test method was introduced and 11 model tests were carried out to analyze the failure modes of the shear plate and the factors such as the thickness, height, hole diameter, hole diameter in the hole and the presence of perforated reinforcement Shear shear capacity and anti-slip characteristics. The results show that this type of shear has good mechanical properties and economy, especially when the steel bars are perforated in open holes, the shear capacity and ductility of the specimens can be greatly improved.
