In the process of prefabricated hoisting construction,embedded anchors play a decisive role.With the rapid increase of the demand for embedded anchors,it is necessary to deeply study the safety performance of the embedded conditions being used in production.In order to further study the tensile-shear mechanical properties of the embedded anchors,a total of 18 embedded anchors of three categories and three species were selected and designed into 3 groups of 9 base material concrete specimens in this experiment.Through the analysis of the test phenomenon,nine concrete specimens occurres concrete failure.By analyzing the experimental datas and the load-displacement curves,the ultimate bearing capacity of each embedded anchor can be calculated,and the feasibility of the experimental scheme was verified.The test results were substituted into the three standards for checking the calculation formulas for the coupling of tensile-shear.The results show that the calculation method specified in American code ACI 318 is more secure when calculating the tensile-shear force.
