Question 1

The minimum strain at failure in the tensile reinforcement (fy = 420 MPa) of RCC beam at failure as per limit state method is _______× 10—2

Question 2

As per IS:456-2000, with respect to the stripping time of formwork the forms shall not be released until the concrete has achieved a strength of at least ________times the stress to which the concrete may be subjected at the time of removal of formwork.

Question 3

For limit state of collapse, the partial safety factors recommended by IS 456:2000 for estimating the design strength of concrete and reinforcing steel are respectively

Question 4

Un–factored maximum bending moments at a section of a reinforced concrete beam resulting from a frame analysis are 50, 80, 120 and 180 kNm under dead, live, wind and earthquake loads respectively. The design moment (kNm) s per IS : 456–2000 for the limit state of collapse (flexure) is

Question 5

A cantilever beam of width 450 mm and effective depth 550 mm is laterally restrained at a distance L from the free end. The maximum value of ‘L’ to ensure proper stability is
