Question 1

For normal cases, stiffness of a simply supported beam is satisfied if the ratio of its span to its overall depth does not exceed

Question 2

If permissible compressive stress in concrete is 50 kg/cm2, tensile stress in steel is 1400 kg/cm2 and modular ratio is 18, the depth of the beam is
1) 100%
2)  
3)
4)

Question 3

Calculate the effective flange width of the following T-beam:
Thickness of slab = D1=100mm
Width of rib = B =300mm Depth of beam = D =500mm Centre to center distance of beam = 3.0mm Effective span of beam = 6.0mm Distance between points of contra flexure =1 = 3.6m

Question 4

A RCC beam of 200 mm width and 300 mm effective depth is reinforced with Fe415 grade steel. The grade of concrete used is M20. The limiting moment carrying capacity of this beam is

Question 5

What is the over all depth of the slab 3×4m in size to safety vertical deflection limit. The slab is continuous and reinforced with Fe 415 steal.

Question 6

Consider the following statements:
1) A rectangular slab supported from only one direction is called one way slab and a rectangular slab supported from both directions is called two way slab.
2) A rectangular slab is called two way slab only if the aspect ratio of the slab is more than 2.

Question 7

A circular slab subjected to external loading, deflects to form:

Question 8

If l1 and l2 are the lengths of long and short spans of a two way slab simply supported on four edges and carrying a load w per unit area, the ratio of the loads split into w1 and w2 acting on strips parallel to l1 and l2 is

Question 9

Distribution reinforcement in a simply supported slab is provided to distribute _____.

Question 10

The main reinforcement of a RC slab consists of 10 mm bars at 10 cm spacing. If it is desired to replace 10 mm bars by 12 mm bars, then the spacing of 12 mm bars should be ______.
