The Elasto-Plastic Analysis of Two Experimental Portal Frames

Dr. W. G. GODDEN commented that the problem of both transverse and axial forces acting on a laterally unbraced arch rib within the range of elastic action raised two important issues, namely, the application of Southwell’s method, and the evaluation of stress from an assumed deflection profile.
