Summary
Synthesising different collapse mechanisms for indeterminate beams and frames is considered via the prospect of their salient bending moments (without solving for their exact values) as candidate positions for the formation of plastic hinges. The method of Instantaneous Centre is introduced for calculating the relative motion of sub-structures within frames, including those with pitched roofs under distributed loading.
