Abstract: Seismic forces acting on the structure mainly depends onto the weight of structure, the primary theme of this work is to reduce the self-weight of the concrete structures, which can be done by using the structural lightweight concrete, it will help in minimizing the lateral seismic forces on the structure and also helps in reducing the size of the structural members and area of reinforcement required while designing. This paper consists of a comparative study on seismic behaviour of G+15 high-rise building made with structural lightweight concrete (SLWC) and normal weight concrete (NWC) for different soil conditions and different zones, by using SLWC at critical conditions results shown that maximum bending moment and shear force got reduced by 40% and 34% respectively and maximum member sizes and steel reinforcement got reduced by 31% and 38% respectively, it has also been found that seismic forces on the structure got reduced considerably.
Keywords: Seismic Weight, Storey Drift, Base Shear, SLWC, Natural Frequency and Time Period.
Scope of the Article: Seismic Evaluation of Building Nonstructural Components
