P-Delta is a non-linear effect that occurs in every structure where elements are subject to axial load. Due to little knowledge of P-Delta and complexity of analysis, architectures and structural engineers are tempted to perform linear static analysis, which may cause sudden collapse of the structure. To study these effects on multistorey building we are adding shear wall in the structure. With the help of shear wall what are parameter changes in structure we will check. For this topic we made model in ETAB of having shear wall and without shear wall. The objective of this work is to find out the effect of P-Delta analysis (Second-order effects) upon the responses of the structures such as displacement, bending moment, shear forces against the linear static analysis. Also, to study the uses of shear wall in reducing the P-Delta effect.
