Analysis and design of steel unbraced frames bending on both axes were performed with emphasis on stability and deflection checks. Wind-moment design is proposed to improve the stability and stiffness. The performance of the frames was checked for collapse load level at Ultimate Limit State (ULS) for 2nd order anaysis and the deflection limits at Serviceability Limit State checked for Ist order analysis. The investigation demonstrated that the frames should be restricted to less than four storeys.
