Question
A propped cantilever made of a prismatic steel beam is
subjected to a concentrated load P at mid span as
shown.
A
K1.5 m- 1.5 m-IR
If load P = 80 kN, find the reaction R(in kN)
(correct to 1-decimal place) using elastic
analysis.
%3D
If the magnitude of load P is increased till collapse
and the plastic moment carrying capacity of steel
beam section is 90 kNm, determine reaction R
(in kN) (correct to 1-decimal place) using plastic
analysis.
