The Elasto-Plastic Analysis of Two Experimental Portal Frames

Using a stress/strain curve closely representative of the true material properties, the moment/curvature relationship in the elasto-plastic range has been obtained for a batch of rolled steel joists used in the construction of two half-scale rectangular portal frames tested to destruction under combined vertical and horizontal loads. This information forms the basis for an accurate theoretical determination of bending moment distributions and deformations at or near the collapse load as determined by the simple plastic theory.
