Study of the Seismic Behavior of Diagonally Reinforced Concrete Coupling Beam with Compared to Composite Beam

Abstract

Most of the reinforced concrete RC Shear walls have openings have openings due to door, window and transport facilities, which are connected with coupling beam. It is essential to examine the seismic performance of structural elements to guarantee the dependability and safety of structures during earthquakes. In order to increase the overall stiffness and strength of the structural system, coupling beams are essential for transferring lateral forces across structural components. These abstract details an ANSYS-based investigation on the seismic behavior of coupling beams. Comprehensive modeling and analysis of complicated structural systems susceptible to seismic loading is made possible using ANSYS software, a potent finite element analysis tool. In this work, ANSYS is used to create a three-dimensional finite element model of a building with coupling beams. To effectively simulate the structural response to seismic excitation, the model includes realistic material properties, geometry, and boundary conditions. A number of dynamic evaluations are performed to evaluate the coupling beams' seismic response. To comprehend the coupling beams' performance under earthquake loading, evaluation is done of their reactions, including their deformation patterns, stresses. The beam with diagonally reinforcement having maximum deformation of 0.098 mm, where the deflection of conventional beam with steel plate having maximum deformation of 0.1 mm. The percentage difference of maximum deformation is 2%. The conventional beam with steel plate having maximum shear stress of 7.64 MPa, where the deflection of beam with diagonally reinforcement having maximum deformation of 8.5 MPa. As per results, the conventional beam with steel plate gets less shear stress as compare to diagonally reinforcement beam. The percentage difference of maximum shear stress is 10.11%.
