Stability Analysis of Steel Frame Structures: P-Delta Analysis

The Steel structures are gives good performance in High Rise buildings requires Stability and design purposes. This research focused on P-delta analysis to be compare with linear static analysis. In This study, a G+21 storey steel frame structure with 72.6m has been selected to be idealized as multi storey steel building model. This model Is analyzed by using ETABS9.7 software with the consideration of P-delta effect. At the same time the influence of different bracing patterns and different location of X bracings has been investigated. For This reason five types of bracing systems including X, V, single diagonal, Double X, K bracing with unbraced model of same configuration are modeled and analyzed. The frame structure Is analyzed for Wind load as per Is 875 (part 3)-1987. Ofter analysis, the comparitive study Is presented with respective to Maximum storey displacement, story drift and column moments. The present work shows That the ‘X’ bracing in continuous bracing pattern Is proved to be more effective with respect to both static and P-delta analysis. So X bracings are using in different locations This shows That Model-4 Is proved to be more effective for same parameters with respect to Both static and P-delta analysis.
