1. Pick up the correct statement from the following:
Options
A. The effective span of a simply supported beam is clear span plus its effective depth or centre to centre of supports whichever is less
B. The effective span of a simply supported slab is clear span plus its effective depth or centre to centre of supports whichever is less
C. The effective span of a continuous beam or slab is the clear span plus its effective depth or centre to centre of supports whichever is less, provided the width of the support is less than of clear span
D. For spans with roller or rocker bearing, the effective span is the distance between the centres of bearings
2. The distance of the critical section for shear from the periphery of the column or drop panal is at a distance (where d is effective depth of flat slab).
5. Pick up the correct statement from the following:
Options
A. Net sectional area of a tension member is its gross area less deductions for holes
B. Gross diameter of river hole is 1.5 mm in excess of its normal diameter if it is greater than 25 mm
C. Gross diameter of the rivet hole is 2.0 mm in excess of its normal diameter if it is greater than 25 mm
D. The total deduction area for the holes is obtained by the product of the thickness and sum of the diameters of the holes in any chain across the member
