1. An R.C.C. beam of 6 m span is 30 cm wide and has a lever arm of 55 cm. If it carries a U.D.L. of 12 t per m and allowable shear stress is 5 kg/cm2, the beam
   
   1.   Is safe in shear
   2.   Is safe with stirrups
   3.   Needs revision of section
   4.   Is safe with stirrups and inclined bars
2. Lapped splices in tensile reinforcement are generally not used for bars of size larger than
   1.   18 mm diameter
   2.   24 mm diameter
   3.   30 mm diameter
   4.   36 mm diameter
3. Minimum spacing between horizontal parallel reinforcement of the same size should not be less than
   1.   One diameter
   2.   2.5 diameters
   3.   3 diameters
   4.   3.5 diameter
4. If the ratio of the span to the overall depth does not exceed 10, the stiffness of the beam will ordinarily be satisfactory in case of a
   1.   Cantilever
   2.   Simply Supported
   3.   Continuous
   4.   None of these
5. To ensure uniform pressure distribution, the thickness of the foundation, is
   1.   Kept uniform throughout
   2.   Increased gradually towards the edge
   3.   Decreased gradually towards the edge
   4.   Kept zero at the edge
6. According to load factor method, the permissible load ‘W’ on a short column reinforced with longitudinal bars and lateral stirrups, is
   
   1.   Stress in concrete × area of concrete
   2.   Stress in steel × area of steel
   3.   Stress in concrete × area of concrete + Stress in steel × area of steel
   4.   None of these
7. The floor slab of a building is supported on reinforced cement floor beams. The ratio of the end and intermediate spans is kept
   1.   0.7
   2.   0.6
   3.   0.9
   4.   0.8
8. In case the factor of safety against sliding is less than 1.5, a portion of slab is constructed downwards at the end of the heel slab, which is known as
   
   1.   A key
   2.   A rib
   3.   A cut-off wall
   4.   All the Above
9. A foundation rests on
   1.   Base of the foundation
   2.   Sub-grade
   3.   Foundation soil
   4.   Both (b) and (c)
10. An R.C.C. roof slab is designed as a two way slab if
    1.   It supports live loads in both directions
    2.   The ratio of spans in two directions is less than 2
    3.   The slab is continuous over two supports
    4.   The slab is discontinuous at edges
