THE CALCULATION OF COLLAPSE LOADS FOR FRAMED STRUCTURES. (INCLUDES APPENDIX).

Abstract

Synopsis The Paper presents a new method for the determination of the collapse load for structures of any degree of complexity by a simple routine analysis. The method is limited only by the time which would be taken in the analysis for a large frame. It is shown, however, that a skilled analyst may be able to reduce the labour involved to a considerable extent. The method is contrasted with the method which is used at present, in which the designer guesses the locations of the plastic hinges which form when the structure collapses, and then adjusts his guesses in a systematic manner.
