RCC Structures Design Questions

• According to the steel beam theory of doubly reinforced beams
• The spacing of transverse reinforcement of column is decided by the following consideration.
• An under-reinforced section means
• The system in which high tensile alloy steel bars (silica manganese steel) are used as prestressing tendons, is known as
• If C is creep coefficient, f is original prestress in concrete, m is modular ratio, E is Young's modulus of steel and e is shrinkage strain, the combined effect of creep and shrinkage is:
• The maximum shear stress (q) in concrete of a reinforced cement concrete beam is
• The stem of a cantilever retaining wall which retains earth level with top is 6 m. If the angle of repose and weight of the soil per cubic metre are 30° and 2000 kg respectively, the effective width of the stem at the bottom, is
• 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
• If the loading on a prestressed rectangular beam, is uniformly distributed, the tendon to be provided should be .
• If the length of a wall on either side of a lintel opening is at least half of its effective span L, the load W carried by the lintel is equivalent to the weight of brickwork contained in an equilateral triangle, producing a maximum bending moment
• The maximum ratio of span to depth of a slab simply supported and spanning in two directions, is
• For M 150 grade concrete (1:2:4) the moment of resistance factor is
• Pick up the correct statement from the following:
• If longitudinally spanning stairs are casted along with their landings, the maximum bending moment per metre width, is taken as
• Lapped splices in tensile reinforcement are generally not used for bars of size larger than
• According to I.S. : 456, slabs which span in two directions with corners held down, are assumed to be divided in each direction into middle strips and edge strips such that the width of the middle strip, is
• The minimum thickness of a flat slab is taken
• The neutral axis of a T-beam exists
• Minimum spacing between horizontal parallel reinforcement of the same size should not be less than
• The load stress of a section can be reduced by
