The shear capacity of coupling beams placing conventional reinforcements in the wall and core structure of multi-story buildings

Abstract

         In the calculation of wall-core structures in multi-story buildings, it is necessary to mention the presence of coupling beams to increase the efficiency of these types of structures. However, the connecting beam is subjected to a large amount of internal force and tends to fail first. The connecting beam must be calculated to ensure the strength and the stiffness to meet the working requirements of the structural system. There are many studies on the bearing capacity as well as the working of connecting beams both experimentally and on numerical models. However, there has not been a specific survey on the interaction between the longitudinal reinforcement and the transverse reinforcement on the working and shearing capacity of the beam. The article will be based on theoretical research, compare computational models to evaluate the working of the beams based on the content of the two types of reinforcement mentioned above. The results show that the longitudinal reinforcement significantly affects the shear strength of the coupling beam and should be included in the calculation of this type of beam structure
