Comparison of one directional and the two directional rigid frame systems

Every structural system?s behaviors are different from the others. Rigid frames, concentrically and eccentrically braced frames give different results under statical and earthquake loads. From this point of view, different optimum design principles are improved for every structural system. The purpose of this study is to examine structural analysis of the multi storey steel structures with rigid frames, inverse V and X shaped concentrically braced frames according to codes. Statical and earthquake loads of the structural systems are defined and design principles described according to the ABYYHY. The results of the analysis have been revealed and compared. Key words: Multi storey steel structures, rigid frames, concentrically braced steel frames, earthquake analisys of steel structures.
