Question 1

A reinforced concrete beam is subjected to the following bending moments:
BM due to Dead load: 25 kNm
BM due to Live load: 40 kNm
Bm due to Wind load: 10 kNm
BM due to Earthquake load: 15 kNm
The design bending moment (in kNm) of limit state of collapse is

Question 2

If the effective depth and effective cover of a deep continuous beam is 600 mm and 50 mm respectively, then its maximum effective length will be ____ mm.

Question 3

An isolated T-beam as shown in figure is used as a Walk way. The beam is simply supported with an effective span of 7.2 m. The effective width of flange for the given cross section is ________ mm.

Question 4

For a beam of cross–section, width = 230 mm and effective depth = 500 mm, the number of rebars of 12 mm diameter required to satisfy minimum tension reinforcement requirement specified by IS : 456–2000 (assuming grade of steel reinforcement as Fe 500) is _______

Question 5

Consider the singly reinforced beam section given below (left figure). The stress block parameters for the cross–section from IS: 456 : 2000 are also given below (right figure). The moment of resistance for the given section by the limit state method is ________ kN–m.

Question 6

An RC beam, is simply supported over a span of 6 m, having size 250 mm wide and 450 mm deep overall. It is subjected to two point loads W of equal magnitude placed at middle third points. The two loads are gradually increased simultaneously. Beam is reinforced with 3 HYSD bars of 18 mm diameter placed at an effective cover of 50 mm at the bottom face and nominal shear reinforcement has been provided. The characteristic compressive strength and the bending tensile strength of the concrete are 20 N/mm² and 2.2 N/mm² respectively. Neglecting the presence of tension reinforcement, the value of load W (in kN) when the first flexure crack will develop in the beam is
