Abstract
The usefulness of shear walls in the structural planning of multistory buildings has long been recognized .Shear walls are located on each level of the structure, to form an effective box structure, equal length shear walls are placed symmetrically on opposite sides of exterior walls of the building. Shear walls are added to the building interior to provide extra strength and stiffness to the building when the exterior walls cannot provide sufficient strength and stiffness or when the allowable span-width ratio for the floor or roof diaphragm is exceeded. Shear walls are analyzed to resist two types of forces: shear forces and uplift forces. Shear forces are created throughout the height of the wall between the top and bottom shear wall connections. Uplift forces exist on shear walls because the horizontal forces are applied to the top of the wall. These uplift forces try to lift up one end of the wall and push the other end down. In some cases, the uplift force is large enough to tip the wall over. Shear walls are analyzed to the provide necessary lateral strength to resist horizontal forces. Shear walls are strong enough, to transfer these horizontal forces to the next element in the load path below them. The seismic motion that reaches a structure on the surface of the earth is influenced by local soil conditions. The subsurface soil layers underlying the building foundation may amplify the response of the building to earthquake motions originating in the bedrock. Three types soil are considered here:Hard soil ,Medium soil,soft soil. In this paper 30 story building with I Shape RC Shear wall at the center in Concrete Frame Structure with fixed support conditionsunder different type of soil for earthquake zone V as per IS 1893 (part 1) : 2002 in India are analyzed using software ETABS by Dynamic analysis( Response Spectrum method). All the analyses has been carried out as per the Indian Standard code books.This paper aims to Study the behaviour of high rise structure with dual system withI ShapeRC Shear Walls under different type of soil conditionwith seismic loading . Estimation of structural response such as; storey shear, storey drift,storey displacements, storey moment,Pier Forces, column forces ,Time period and frequency,Stiffness, Mode shape of shear walls is carried out.
