kinematic method

A prismatic steel beam is shown in the figure. The plastic moment, M_p calculated for the collapse mechanism using static method and kinematic method is

A propped cantilever of span $$L$$ carries a vertical concentrated load at the mid-span. If the plastic moment capacity of the section is $${M_P}$$, the magnitude of the collapse l...

For a fixed beam with span $$L,$$ having plastic moment capacity of $${{M_p}}$$, the ultimate central concentrated load will be
