According to IS : 800 - 71, the minimum thickness of a vertically stiffened web plate, shall not be less thanAnswer: d/250 A fillet weld may be termed asAnswer: all the above. Pick up the correct statement from the following:Answer: All the above. A structural member subjected to compressive stress in a direction parallel to its longitudinal axis, is generally known asAnswer: all the above. Live loadAnswer: All the above. The most economical section for a column, isAnswer: tubular section If the depth of two column sections are equal, then the column splice is providedAnswer: none of these. The distance between e.g. of compression and e.g. of tension flanges of a plate girder, is known asAnswer: effective depth Web crippling generally occurs at the point whereAnswer: concentrated loads act Pick up the incorrect statement from the following:Answer: The diameter of a rivet hole is equal to the nominal diameter of the rivet plus 1.5 mm When a tension member is made of four angles with a plate as a web, the allowance for holes is made asAnswer: one hole for each angle and two holes for the web The failure of a web plate takes place by yielding if the ratio of the clear depth to thickness of the web, is less thanAnswer: 82 The minimum edge distance of a rivet line connecting two or more plates, is kept equal to 37 mm plus (where t is the thickness in mm of the thinner outside plate).Answer: 4 t Pick up the correct statement from the following:Answer: Dead load includes self-weight of the structure and super-imposed loads permanently attached to the structure The maximum permissible slenderness ratio of a member carrying loads resulting from wind, isAnswer: 250 If d is the distance between the flange angles, the vertical stiffeners in plate girders are spaced not greater thanAnswer: 1.5 d If the unsupported length of a stanchion is 4 metres and least radius of gyration of its cross-section is 5, the slenderness ratio of the stanchion, isAnswer: 80 For a rectangular section, the ratio of the maximum and average shear stresses, isAnswer: 1.5 To keep the intensity of bearing pressure between the column base and concrete compressive and to vary from zero to 2P/BL, the ratio of the moment M to the axial load P should beAnswer: L/6 The cross-section of a standard fillet is a triangle whose base angles areAnswer: 45° and 45° Secant formula for direct stress in compression, is applicable only for slenderness ratio uptoAnswer: 140 A second horizontal stiffener is always placed at the neutral axis of the girder if the thickness of the web is less thanAnswer: both (c) and (b) The rolled steel I-sections are most commonly used as beams because these provideAnswer: all the above. The thickness t of a single flat lacing should not be less thanAnswer: 1/40 th length between inner end rivets For the steel member exposed to weather and accessible for repainting, the thickness of steel should not be less than (excepting the webs of Indian Standard rolled steel joists and channels).Answer: 6 mm Column footing is providedAnswer: all the above.
