Shear Effect on the Elastic Stability of Frames

Modified stability functions for prismatic beam-columns having any solid cross-sectional shapes, laced or battened built-up structural members, are developed in terms of the shear flexibility and axial load parameters. They make possible the rapid prediction of the elastic critical load of structures taking into consideration the effect of shear force in the members, using a hand-computing method. The modified stability functions are related to existing tabulated stability of prismatic strut. The approximate formulae predict the accurate elastic critical load to within 1%. S.Z. Al-Sarraf
