If the rivets in adjacent rows are staggered and outermost row has only one rivet, the arrangement of the rivets, is calledAnswer: diamond riveting The energy stored in a beam of length L subjected to a constant B.M. isAnswer: M²L/2EI The area of the concrete in compression plus the area of reinforcement transferred on the basis of modular ratio, is calledAnswer: cracked section If D is the overall thickness of the slab, the diameter of the reinforcing bars should not exceedAnswer: 1/8 D The gap between web plates and flange plates for fillet welds should not be more thanAnswer: 1.5 mm A continuous beam shall be deemed to be a deep beam if the ratio of its effective span to overall depth, isAnswer: less than 2.5 The depth 'd' of webs without horizontal stiffeners and consisting of tongue plates is taken lesser than the depth of the girder between the flanges less the sum of the depth of the tongue plates, andAnswer: eight times the sum of the thickness of tongue plates For design of a column the eccentricity of loading shall be taken as the distance from the assumed point of application of the load to the centroid of the column, subject to a minimum ofAnswer: 50 mm The maximum area of compression reinforcement in a beam of cross section B x D is limited toAnswer: 0.04 BD Moist curing of the exposed surfaces of concrete is done at least forAnswer: 7 days Pick up the incorrect statement from the following:Answer: The gross section of the web of channels is the depth of the web multiplied by its thickness If the ratio of effective span to overall depth of a simply supported beam is equal or greater than 1 but less than or equal to 2, the lever arm, isAnswer: 0.2 (l + 2D) If the slenderness ratio of a column is more than 160, the compressive stress obtained by the secant formula is multiplied by a factor( x_1/800r ) in which value of x isAnswer: 1.5 For battened struts, the effective length is increased byAnswer: 10% The maximum horizontal deflection of a column of actual length L, when subjected to lateral forces, may be uptoAnswer: L/325 The test strength of the sample is taken as the average of the strength ofAnswer: 3 specimens The maximum deflection of a structure should not normally exceed lesser of the span/350 orAnswer: 20 mm Pick up the correct statement regarding columns.Answer: All the above. For heavily reinforced concrete member, the nominal maximum size of the aggregates should be restricted toAnswer: smaller of (a) and (b) The minimum pitch i.e., the distance between centres of rivet holes is not less thanAnswer: 2.5 times the hole diameter Dispersion of load through the flange to web is considered as dispersed uniformly at an angle θ° isAnswer: 30° The grade of concrete generally not used in the reinforced concrete, isAnswer: M 10 The outstand of stiffeners should be (where t is the thickness of flat).Answer: 12 t For the plain reinforcing bars in compression, the permissible design bond stress in tension, is increased byAnswer: 25% The cover to the main reinforced may be reduced up to one third of the specified cover but not less thanAnswer: 5 mm The reduced level of third floor of a building near a column is 205.350 m. The reduced levels of the undersides of four beams supporting the fourth floor framing into the column mutually perpendicular are 208.350 m, 208.450 m, 208.500 m and 208.550 m. The supported length of the column isAnswer: 3.000 m The distance between, rivet line and the nearest edge of a joint not exposed to weather, is taken (where t is thickness in mm of the thinner outside plate).Answer: 12 t Pick up the correct precaution while spilicing the reinforcing barsAnswer: All the above. The over all depth of a solid slab is 20 cm and effective depth is 15 cm. The horizontal distance between parallel main reinforcement should not be more thanAnswer: 45 cm The ratio of minimum compressive strength on 15 cm cubes prepared with the concrete of M 20 grade and M 40 grade, at 7 days should be at leastAnswer: 1/2
