Dynamic Analysis of High Rise RC Structure with Shear Walls and Coupled Shear Walls

Abstract

Among the dangerous natural hazards earthquake is the one which, cause great damage of life and
livelihood. The ground motion and the structure itself are the characteristics on which the response of the structure
depends during an earthquake. The high in plane stiffness and strength of the shear wall systems helps to resist both
large horizontal load and gravity load. Now a days in order to resist lateral loads in the high rise buildings, the shear
wall systems are commonly used. The present study carried out helps in determining the response of a high rise RC
Frame structure with shear walls, coupled shear walls and equivalent coupled shear wall systems. To study the behavior
of the system, parameters such as base shear, storey shear, storey drift, displacements and member forces are
considered. The above systems with shear wall are compared with the bare frame without any shear wall and coupled
shear wall. The effect on the high rise building systems, built in the very sever seismic zones will be studied and
compared. For the present study 30, 40 and 50 storied RC Frame structures are considered and analyzed with and
without shear wall system, and effectiveness of bare frame with only shear walls, coupled shear walls and combination of
both i.e., equivalent coupled walls are found out and best of the three systems for particular height of the building is
suggested.
