Question 1

A pole AC is kept vertical by using two inclined ropes as shown in figure below. Before application of load at top, tension in rope is just greater than zero. If a point load is applied at 'A', then the BM at B will be

Question 2

A two hinged semicircular arch of radius 30 metres carries a load system shown in the figure. The horizontal thrust at each support is _________ kN.

Question 3

Consider the following statements. Which of the following statement (s) is (are) CORRECT?
Statement I: In the elastic-plastic behavior of statically indeterminate structure the ultimate load can be calculated from equilibrium considerations without any reference to the stiffness characteristics of the structure.
Statement II: The ultimate load of a structure is influenced by settlement of supports, thermal stresses and residual stresses.

Question 4

The degree of freedom of the beam shown is?

Question 5

All members of the frame shown below have the same flexural rigidity EI and length L. If a moment M is applied at joint O, then the rotation of the joint O is

Question 6

Which of the following statements are true?
1) Slope deflection method is always used for determinate structures.
2) Slope deflection method is displacement method.
3) Modified slope deflection equation is used when one support is hinged.
4) Superposition cannot be applied in slope deflection equations.

Question 7

Consider the propped cantilever shown in figure (a) and fixed beam shown in figure (b).

Consider the following statements:

Statement I: Fixed end moment at A for propped cantilever is 12 t-m.

Statement II: Fixed end moment at A for fixed beam is 6 t-m.

Question 8

Identify the correct deflected shape corresponding to the loading in the plane frame shown below:
