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.
