为了探究PBL剪力连接件构造参数对其抗剪承载力的影响,以哈工大推出试验为原型,基于ANSYS软件建立了有限元分析模型,通过改变剪力连接件的构造参数,研究了抗剪承载力的变化规律。结果表明:PBL剪力连接件的承载力随着混凝土强度等级、钢板开孔直径、贯穿钢筋直径的增加而增大;当钢板开孔直径为30mm时,贯穿钢筋的合理直径为16mm;适当增加钢板厚度,有助于提高PBL剪力连接件的抗剪承载力。研究结果为下一步合理设计PBL剪力连接件奠定了理论基础。
In order to investigate the influence of the structural parameters of PBL shear connectors on its shear capacity, a prototype of the Harbin Engineering University launching test was taken as the prototype. Based on the ANSYS software, a finite element model was established. By changing the structural parameters of the shear connectors, The law of change of force. The results show that the bearing capacity of PBL shear connectors increases with the increase of concrete strength, the diameter of steel plate and the diameter of steel bar. When the diameter of steel plate is 30mm, the reasonable diameter of steel bar is 16mm. The thickness of the steel sheet helps to increase the shear capacity of PBL shear connectors. The research results laid a theoretical foundation for the rational design of PBL shear connectors in the next step.
