Q4
Figure Q4(a) shows the idealized stress-strain curve for steel and Figure Q4(b) shows
the yielding of the beam section due to bending. Explain in detail the relation between
these TWO (2) Figures based on your understanding of plastic analysis.
(а)
(b)
Figure Q4(c) shows a continuous beam subjected to uniformly distributed load at span
AB and span EF. Span BE of the continuous beam is subjected to the concentrated
load of 10 kN and 20 kN at C and D, respectively.
(i)
With the aid of sketches, identify all the possible collapse mechanism of the
beam and label the corresponding plastic hinges, plastic moment (Mp) and
rotation (0).
(ii)
Virtual work is one of the methods that can be used to analyze plastic moment
(Mp). State the principle of virtual work, then by using this method, determine
the maximum plastic moment, (Mp) of the continuous beam.
