l. Determine the ultimate moment of resistance for the T-beam section of effective width of 850 mm shown below (Fig. l). Assume M20 grade concrete and Fe 250 grade steel. (40)
2. Design shear-reinforcement for the doubly rein forced beam shown in Fig. 2. The beam is simply supported with a total centre-to-centre span of 6.0 m. Use 8mm<p vertical stirrups made of Fe 250 steel. The shear at the bar-cutoff point (860 mm from centre of support) also needs to be checked. The concrete is of M25 and flexural steel of Fe 415. (40)
3. A pretensioned beam 200 mm wide and 300 mm deep is prepossessed by 10 wires of 7 mm diameter initially stressed to 1200 N/mm2, with their centroids located 100 mm from the so fit. Find the maximum stress in concrete immediately after transfer, allowing only for elastic shortening of concrete.
If the concrete undergoes further shortening due to creep and shrinkage while there relaxation of 5 oh steel stress, estimate the percentage loss of stress in the wires, using the code (lS I 343- 1980) regulations, and the following data
E = 210 kN/mm2
E = 57oo (t,)”‘
fcu = 42 N/mm2
Creep coefficient q : 1.6
Total residual shrinkage strain : 300E-6
4. Generate the stiffness matrix for the beam with respect the coordinates shown in the Fig.3 (40)
5. Find the collapse load for the portal frame shown (40)
6. A 300 I.S.F 8 mm is used as a tension member in a lattice girder. It is connected to gusset plate by l8 mm q hand-driven rivets. The yield stress of steel is 250 N/mm the maximum force that the member can carry, if a 12 mm . Calculate
a) Chain riveting is done as shown in Fig. 5a
b) Zig-zag riveting is done as shown in Fig. 5b
7. A recrangular block 250 mm x 100 mm x 80 mm is subjected to axial loads as follows (40)
480 kN tensile in the direction of its length
900 kN tensile on the 250 mm x 80 mm faces
1000 kN compressive on the 250 mm x 100 mm faces
Assuming Poissons’s ratio as 0.25, and Young’s modulus to be 2E-5 N/mm’, evaluate the following.
(i) Volumetric strain
(ii) the change in volume of the block due to the application of the above load
(iii) Modulus of rigidity and bulk modulus for the material
