One of the most popular methods of lateral retrofit of braced steel frame is using diagonal steel bracing which is famous for CBF bracing. Because of its easy operation and independence of any specific designing requirements, it happens to be the first choice of designers. Yet this bracing, in spite of having great and considerable difficulty, includes some weaknesses like low rate of deformation in comparison to EBF bracing. In this paper an eight floor steel frame structure in various bracing condition such as two kinds of CBFt bracing and three kinds of EBF bracing and one bending frame without bracing is being used and it is being analyzed by Static analysis method and then parameters such as lateral displacement , axial force , and an specified moment of a column is being compared and investigated.
