1) The live load to be considered for an accessible roof, is
2) For a continuous floor slab supported on beams, the ratio of end span length and intermediate span length, is
3) The minimum head room over a stair must be
4) On piles, the drop must be at least
5) According to I.S.: 456, 1978 the thickness of reinforced concrete footing on piles at its edges, is kept less than
6) For normal cases, stiffness of a simply supported beam is satisfied if the ratio of its span to its overall depth does not exceed
7) In testing a pile by load test, pile platform is loaded with one and half times the design load and a maximum settlement is noted. The load is gradually removed and the consequent rebound is measured. For a safe pile, the net settlement (i.e. total settlement minus rebound) per tonne of test load should not exceed
8) Lapped splices in tensile reinforcement are generally not used for bars of size larger than
9) A foundation is called shallow if its depth, is
10) An R.C.C beam of 25 cm width has a clear span of 5 metres and carries a U.D.L. of 2000 kg/m inclusive of its self weight. If the lever arm of the section is 45 cm., the beam is\
11) 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
12) The allowable tensile stress in mild steel stirrups, reinforced cement concrete, is
13) The floor slab of a building is supported on reinforced cement floor beams. The ratio of the end and intermediate spans is kept
14) If the width of the foundation for two equal columns is restricted, the shape of the footing generally adopted, is
15) The ratio of the breadth to effective depth of a beam is kept
16) he diameter of the column head support a flat slab, is generally kept
17) The diameter of transverse reinforcement of columns should be equal to one-fourth of the diameter of the main steel rods but not less than
18) A circular slab subjected to external loading, deflects to form a
19) The steel generally used in R.C.C. work, is
20) The self-weight of the footing, is
21) In a slab, the pitch of the main reinforcement should not exceed its effective depth
22) If the length of an intermediate span of a continuous slab is 5m, the length of the end span is kept
23) Spacing of stirrups in a rectangular beam, is
24) In a prestressed member it is advisable to use
25) An under-reinforced section means
