Dynamic Analysis of Irregular Building under Lateral Load with Combination of shear wall with Friction Dampers and Bracings

Abstract

The application of the shear wall system in reinforced concrete (RC) buildings has become widely used to minimize seismic consequences. Besides, the buildings using concentrated steel bracings system are used for the same reasons in steel structures buildings. Both of the systems have significance of the structural performance. Although both systems are used for same the reasons, their effect shows unequal variations and behaviour against seismic load. This is for the reason that the values of response factors are miscellaneous for varying structural systems. This study contains a numerical approach to show dissimilarity between the shear wall system and steel bracing system. Earthquake is the natural calamity, it produce strong ground motions which affect the structure. Small or weak motions that can or cannot be felt by the humans. Provision of shear walls and bracings are installed to can enhance the lateral stiffness, ductility, minimum lateral displacements and safety of the structure. Storey drift and lateral displacements are the critical issues in seismic design of buildings
