Abstract

The buildings are prone to deform laterally from original position with an eccentricity during an earthquake. When building structures are subjected to seismic loading causing the structure to deform, the resulting eccentricity of the total gravity load due to inclined axes of structure causes the extra moments at the base. The presence of infill, bracing and number of storeys may affect the additional displacement due to P-Delta. In the present study, the design parameters of buildings which are affected by P-Delta, such as lateral displacement, base shear, and moment at the base-columns are discussed. The non-iterative P-Delta analysis is adopted to determine the P-Delta effect for symmetric rectangular regular plan structures. It has been reported that, the bare frame Reinforced Concrete (RC) structures more than 20 stories are required to be analysed and designed for P-Delta effect. The P-Delta effect significantly controlled by the braced systems and masonry infill structures.
