The need for adequate resistance against seismic forces is particularly highlighted as a consequence of the rapid urbanization and the demand for high rise structures. Although Reinforced Cement Concrete (RCC) moment-resisting frame (MRF) buildings are very popular in the construction industry due to their strength, durability and architectural flexibility, they are generally too flexible in respect of lateral stiffness for seismic safety in tall buildings. Various systems of bracing are used in RCC frames for improving structural stability and control of the lateral displacements. The purpose of this comparative seismic analysis is to demonstrate that the G+20 RCC moment resisting frame structure outperforms the G+10 structure under Seismic Zone III loading conditions as specified in IS 1893 (Part 1):2002. The analysis was carried out using STAAD.Pro software and included four different bracing configurations: center, corner, horizontal (HZ), and zigzag. The structural response was evaluated in terms of lateral displacement, storey drift, storey shear, stiffness, base shear, and material consumption. The results reveal that the Zigzag and HZ bracing systems considerably improve lateral stiffness while reducing displacement and drift in comparison to the conventional bracing systems. Using STAAD, four distinct bracing configurations—Center, Corner, Horizontal (HZ), and Zigzag—were examined. Advanced program. We looked at the structural response in terms of material consumption, stiffness, base shear, lateral displacement, storey drift, and storey shear.
