Nonlinear behavior of flat slab using shear wall

Abstract

Flat slab is a reinforced concrete slab supported directly by concrete columns without the use of beams.However; in multi-storey buildings it has weak resistance to the lateral loads. Hence this work is concerned to decrease the damage under lateral loading and to minimize the displacement. Shear wall are used to provide stability to structures from lateral loads. The aim of the present study is to analyze effect of shear wall and perimeter beam for flat slab building, and also effectiveness of core shear wall. For present work five models are studied 1) conventional slab building 2) simple flat slab building considered without any drop and column head 3) flat slab with drop building is considered without column head 4) flat slab with drop with perimeter beam building 5) flat slab with perimeter beam and shear wall buildings, each of plan size 25mX25m are selected. For stabilization of structural parameters, shear wall are provided. The seismic parametric studies comprise of roof displacement, base shear, and sequence of hinge formation. from study it concluded that the shear walls significantly increases the base shear capacity and reduces roof displacement and also getting good Performance.
