Question 1

The correct sequence of steps for a static method is
1) Remove redundant forces
2) Calculate degree of static indeterminacy
3) Draw BMD due of the statically determinate structure and BMD due to redundant forces
4) Solve the equations of equilibrium to find the ultimate load
5) Superimpose the moment diagrams to form a mechanism

Question 2

For the following portal frame (AB=BD=DE) the location of hinge formation is

Question 3

If the section shown in the figure turns from fully-elastic to fully-plastic, the depth of neutral axis (N.A.), decreases by

All dimensions are in mm

Question 4

Find the ultimate load for the structure.

Question 5

A continuous beam is loaded as shown in the figure below. Assuming plastic moment capacity equal to Mp, the minimum load at which the beam would collapse is

Question 6

A portal frame ABCD fixed at its base carrying a horizontal sway load P acting at B from left to right. All members have the same section. What is the value of p for the condition that collapse may occur by sway mechanism?
