Analysis of Conventional Chevron Braced Frame and Diagrid Frame with Plan Irregularity

High-rise buildings are more vulnerable to collapse due to high wind and earthquake pressure. In such a building risk of failure can be minimized by adopting lateral load resisting system. In this study, we compared three lateral load resisting frame i.e. diagrid frame and chevron braced frame with conventional frame system. The seismic analysis is done on these three frames. The structures are analyzed by linear static method. The building is considered to be irregular in plan. For irregular plan, C-shape plan, T-shape plan considered. The results are obtained after analysis are compared by various parameters like storey drift, absolute displacement, base shear, moment and axial forces. The First Comparison is between diagrid system, chevron braced system and conventional frame system for C-Type and T-Plan separately and after that second overall comparison is between C-Plan and T- plan. The analysis is done on by using STAAD Software. The result of work showed that diagrid system resist lateral more efficiently than chevron braced system and conventional frame system as it yields the least value for absolute displacement, storey drift, top storey shear and base shear.
