Abstract: The most suitable choices in improvement of reinforcement concrete structures against lateral loading is to provide steel bracing system. The use of steel bracing has potential advantage over other scheme like higher strength and stiffness, economical, occupies less space, adds much less weight to existing structure. In this study, the analysis of a reinforced concrete (RC) irregular building (H-Shaped) with different types of bracing (Diagonal, V type, inverted V type, X type, K type) is carried out by using ETABS software. For this purpose response spectrum method is taken into consideration and results are obtained in ETABS. The buildings are located in zone III region. The main parameters considered in this paper are lateral displacement, storey drift, axial force, base shear, joint displacement.
