摘要
基于8组PBL键试件试验结果,采用ANSYS有限元方法进行数值分析,研究PBL键荷载-滑移、静力学特性及传力机理,并将计算结果和试验进行对比,结果表明:计算结果与试验值吻合较好,在不具备试验条件下,可采用本文数值分析方法确定PBL键的静力学特性,为钢-混结合段PBL键的理论研究和设计分析提供参考。
Based on the test results of 8 groups of PBL shear key specimens,the ANSYS finite element method is used for numerical analysis,The load slip,static characteristics and force transfer mechanism of PBL bond are studied,and the calculated results are compared with the experimental results.The results show that the calculated results are in good agreement with the experimental data,In the absence of test conditions,The static properties of PBL bond can be determined by the numerical analysis method,It provides a reference for the theoretical research and design analysis of PBL bond in steel-concrete bonding section.
