Comparative seismic performance and material efficiency analysis of g+10 and g+20 rcc moment-resisting frame buildings with various bracing configurations
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.
