Question

Among which of the following is the location of plastic hinge?

(a) at supports

(b) at centre of beam

(c) at points away from concentrated load

(d) at centre for uniformly distributed load

This question was addressed to me in class test.

My doubt is from Plastic-Collapse Load in portion Plastic and Local Buckling Behaviour of Steel of Design of Steel Structures

Answer 1

Right answer is (a) at supports

The explanation is: Plastic hinges normally occur at supports, points of concentrated load, and points where cross section change. The location of plastic hinge in a beam with uniformly distributed load is not well defined.
