The influence study of league shear wall seismic capacity by the coupling wall-beam rigidity and reinforcement ratio

摘要

According to the important role of the league shear wall seismic capacity in the practical engineering, a brief and effective finite element static push-over analysis model was established through using the MIDAS GEN7.95. With the changes in the coupling beam rigidity and reinforcement ratio, the structural base shear, structural failure displacement change during the simulation. On the basis, the curve of the coupling wall-beam rigidity, reinforcement ratio vs. base shear and failure displacement were built respectively. The results show that the coupling wall beam stiffness, reinforcement ratio and league shear wall seismic capacity have a significant effect relationship, which provides an important reference for shear wall seismic design of structures.
