Flat Slab Shear Wall Interaction for Multistoried Building under Seismic Forces”
In present era, scarcity of space led to the development of tall buildings in urban areas. Generally conventional
RC framed structures are used for design and construction of these buildings. Flat plate and flat slab are mostly
used structural forms in RC construction in residential, industrial and commercial buildings in many areas of the
world. This system provides many advantages in terms of use of space, reduce cost of formwork, shorter construction time, architectural flexibility as it require least storey height and easy installation. However, in multi-storey buildings it has week resistance to the lateral loads. Hence this work is concerned to increase the lateral stiffness of building having flat slab and to minimize the displacement under lateral loading. To provide stability to structures from seismic loads, shear wall are used. The aim of the present study is to compare the behavior of multi-storeyed building of conventional R.C.C.,having flat slab with or without shear walls and to analyze the effect of building height on the
performance under earthquake forces. Also effect of with or without shear wall for flat slab building on seismic behavior with varying thickness and varying position of shear wall are studied. In this work, the effects of seismic forces in zone V on these buildings are also carried out. For this, G+9, G+18, G+27 and G+36 Storeyed models, each of plan size 20X20m are selected. For stabilization of the variable parameters, shear wall are provided at different locations. To study the effect of different location of shear wall on flat slab multi-storey building, static analysis (Equivalent Static Analysis) in software STAAD Pro is carried out for zone V. The seismic parametric studies comprise of lateral displacement, storey drift, drift reduction factor and contribution factor.
