According to force component modes of bracing system in Technical Specification for Steel Structure of Light-weight Building with Gabled Frames ( CECS102:98), the exact force components of the bracing system in light steel structure are calculated by a program. The comparative analysis between the exact values and approximants calculated by simplified method is performed. The reasonable design for the members in the bracing system is suggested.
