ELASTIC-PLASTIC ULTIMATE STRENGTH OF GABLE TYPED RIGID FRAMES WITH H SHAPED STEEL SECTIONS : (I) Ultimate Vertical Strength based on Slope-deflection Method considered Axial Forces

Abstract

Elastic-plastic ultimate strengthes of gable typed rigid frames were examined against the symmetrically distributed vertical loads using the elastic-plastic buckling analysis method. As the result of parametric study about various gable typed frames, we obtained the criterion of necessary slenderness ratio of frames to prevent the elastic-plastic asymmetrical buckling preceding the mechanism by simple plastic theory.
