In the construction of the core tube of high-rise and super high-rise steel frame-concrete mixed structure,the construction technology of sliding form and climbing form has been widely used.However,in actual engineering,concrete secondary beams are often used inside the core tube,which limits the application of sliding form and climbing form construction technology.To solve this problem,a grooved shear wall-concrete beam joint was proposed.On the basis of the loading test of 3 grooved shear wall-concrete beam joints with different grooved sizes,the finite element software ABAQUS was used to simulate 3 wall beam joints,and the finite element calculation results were compared with the test results.The results show that the grooved shear wall-concrete beam joint has good bearing capacity,and the yield load differs greatly from the ultimate load.The groove structure can improve the shear resistance of the joint,and the section size of the groove is the main reason for the improvement of the shear resistance of grooved shear wall-concrete beam joint.
