Abstract
In the present scenario of construction industry, time of construction is very crucial factor. Pre-cast construction is gaining significance in general and urban areas in particular. The precast technology is a viable and alternative technique to reduce the construction time. G+11 storey live project is taken for analysis and design with load bearing walls. Design of precast wall panels and design of precast slabs is carried using Indian codes subjected to gravity and lateral loads (seismic and wind). Connections of wall to wall, wall to slab and foundation beam to wall is designed. The structural system consists of load bearing walls and one-way slabs for gravity and lateral loads have been taken for analysis using ETABS. Various wall forces, displacements and moments have been worked out for different load combinations. Data base is presented for the worst load combination. Lateral load on a multistory building is most critical one to consider for the design. In order to observe the seismic effect and wind effect on multi-story building, a study on precast load bearing wall of G+11 has been carried out. Four different seismic zones and all wind zones are considered for analysis using ETABS. The structural response due to lateral loads with load combination is extracted. Effect of lateral load on out-of-plane moments, axial forces, shear force, base shear, maximum storey drift and tensile forces on shear wall are plotted. Finally the effect of seismic zone and wind zone is tabulated
