Question 1

A propped cantilever of span L is subjected to a concentrated load at midspan. If

is the plastic moment capacity of the beam, the value of collapse load will be

Question 2

If a uniform beam shown in the figure below has the plastic moment capacity

for span AB and 0.9

for span BC, what is the correct virtual work equation?

Question 3

What is the number of plastic hinges which will cause the overall total collapse of a structure?

Question 4

The figure below shows a fixed beam of elastic material possessing sufficient ductility and of a uniform cross-section. It carries a uniformly distributed load which is gradually increased to its ultimate value

per unit length, at which the beam is transformed into a failure mechanism. What is the magnitude of

in terms of the ultimate moment

of the beam-section and span L?

Question 5

A load P is applied at the middle of a simply supported beam of span L. If the beam is made of ductile material, and

is the plastic moment, what is the ultimate value of P?

Question 6

Which one of the following is the correct maximum shear capacity of a prismatic beam under plastic design of steel structures?

Question 7

For a vertical stiffened web of a plate girder, the lesser clear dimension of the panel should not exceed (‘t’ is the thickness of the web)

Question 8

A welded plate girder has a web plate 1500 mm × 6 mm. Which one of the following is correct about stiffening the web?

Question 9

For an I-beam, the shape factor is 1.12; the factor of safety in bending stress is 1.5. If the allowable stress is increased by 20% for wind or earthquake loads, then the load factor is

Question 10

How are structural members composed of two angles back to back connected throughout their length?
