Analysis of various thicknesses of Shear Wall with Opening and without Opening and their Percentage Reinforcement

Abstract

Due to increase in population spacing in

India is needed, especially in urban areas. Structural

engineers in the seismic regions across the world often face

the pressure to design high rise buildings with stiffness

irregularities, even though they know these buildings are

vulnerable under seismic loading. Today’s tall buildings are

becoming more and more slender, leading to the possibility

of more sway in comparison with earlier high rise buildings.

Improving the structural systems of tall buildings can

control their dynamic response. With more appropriate

structural forms such as shear walls and improved material

properties. Lateral forces of wind and earthquake are

usually resisted by shear walls which are parallel to the

direction of lateral load. These shear walls, by their

shearing resistance and resistance to overturning, transfer

the lateral loads to the foundation. In the seismic design of

buildings, reinforced concrete structural walls, or shear

walls, act as major earthquake resisting members. The

properties of these seismic shear walls dominate the

response of the buildings, and therefore, it is important to

evaluate the seismic response of the walls appropriately. A

shear wall may contain many openings due to the functional

requirements such as doors and windows, which may

largely affect the overall seismic response of the structure.

An earthquake load is applied to a building of ten stories

located in zone V. In this present study, main focus is to

determine effectiveness of shear wall with various

thicknesses, and also vertical opening, staggered opening

and without opening has been studied with the help of

different models and also analysis and observe the

behaviour of shear wall with and without openings in shear

wall under seismic loads.
