Steel Structure Design Online Test – Multiple Choice Questions and Answers 1. Spans of continuous fillers are considered approximately equal if the longest span does not exceed the shortest span by more than 5% 10% 15% 25% 2. For double angles carrying tension, placed back to back and connected to either side of the gusset plate, the sectional area of the section, is equal to cross sectional area of the section minus area of rivet holes the section multiplied by the area of the rivet hole the section plus area of rivet holes the section 3. The most commonly used sections in lateral system to carry shear force in built up columns, are rolled steel flats rolled angles rolled channels All 4. The maximum axial load which is just sufficient to keep a column in a small deflected shape, is called crippling load buckling load critical load All 5. A simply supported beam carrying a central load, will be safe in deflection if the ratio of its span to depth, is < 24 > 24 < 19 > 19 6. For a steel grillage footing to support two unequal column loads projections of beams on either side in lower tier are such that bending moments under columns are equal trapezoidal shape is used for the base footing bending moment under the columns are kept equal to the bending moment between to two columns All 7. The minimum pitch of rivet holes of diameter d should not be less than 1.25 d 2 d 1.5 d 2.5 d 8. The slenderness ratio of a column is zero when its length is between the points of zero moments is zero is equal to its radius of gyration is supported on all sides throughout its length 9. Poisson’s ratio for steel within elastic limit, ranges from 0.25 to 0.24 0.25 to 0.33 0.15 to 0.20 0.33 to 0.35 10. When a large value of radius of gyration is not required channel flanges are kept outward channel flanges are kept inward channels are placed back to back none of these Loading … Question 1 of 10
