QUESTIONS & SOLUTIONS WITH EXPLANATIONS
Question 34: A doubly reinforced beam is considered less economical than a singly reinforced beam because
(a) Concrete is not stressed to full value
(b) Tensile steel required is more than that for a balanced section
(c) Shear reinforcement is more
(d) Compressive steel is under stressed
Answer – (d)
The doubly reinforced beam is less economical than singly reinforced beam because Compressive steel remains under stress in doubly reinforced beam. steel is 10 times costlier than the concrete. The depth reduces but the cost due to steel in compression zone increases.
Question 38: In prestressed concrete
(a)Forces of tension and compression change but lever are remains unchanged
(b) Forces of tension and compression remain unchanged but lever arm changes with the moment
(c) Both forces of tension and compression and lever arm change
(d) Both forces of tension and compression and lever arm remain unchanged
Answer – (b)
In pre-stressed concrete forces of tension and compression remains unchanged but lever arm changes with moment.
Question 41: When shear stress exceeds the permissible limit in a slab, then it is reduced by
(a) Decreasing the depth
(b) Providing shear reinforcement
(c) Using high strength steel
(d) Increasing the depth
Answer – (d)
Shear stress in slabs is controlled by increasing the depth of slab and not shear reinforcement while in beams shear stirrups are provided to control shear.
Question 46: The channels are angles in the compression chords of the steel truss girder bridges are turned outward in order to increase
(a) cross-sectional area
(b) section modulus
(c) torsional constant
(d) radius of gyration
Answer – (d)
Channels or Angles in the compression chords of the steel truss girder bridges are turned outward in order to increase the radius of gyration which reduces the slenderness ratio of the member. Hence it increases resistance against buckling.
Question 47: Horizontal stiffener in a plate girder is provided to safeguard against
(a) shear buckling of web plate
(b) compression buckling of web plate
(c) yielding
(d) all of the above
Answer – (b)
Horizontal stiffeners in a plate girder is provided to safeguard against compression buckling of web plate. Horizontal stiffeners are also called longitudinal stiffeners.
