OR- a)
Q2
- [18]
Design a simply supported reinforced concrete floor beam B10 as shown in Figure 1 with following data: i) Center to center Span of beam = 3.73 m ii) Width of supporting columns = 300mm iii) Beam width = 230 mm iv) The beam supports slab of thickness 120mm on both side of beam v) For slab-Live load = 2kN/m 2 ; Floor finish = 1.0 kN/m 2 vi) The wall on this beam is 120 mm thick and 2.7 m high. vii) Material- M25, Fe 500. Show details of reinforcement along with zoning of shear reinforcement. UseLSM 2
Q3

Design a continuous floor beam B11-B12-B13 as shown in Figure 1 using IS code coefficients. Thickness of the all floor slab is 130 mm, live load and floor finish load on all slabs are 2.5 kN/m 2 and 1.5 kN/m 2 , respectively. The wall on this beam is 230 mm thick and 2.6 m high. Use M 30 and Fe 500 steel. Design longitudinal reinforcement for all the spans and support for flexure. Design shear reinforcement only for beam B12. Draw neat sketch showing details of main and shear reinforcement. Use LSM.

Design a continuous floor beam B17-B23 (A-B-C) as shown in Figure 1 using moment redistribution method. Thickness of the all floor slab is 130 mm, live load and floor finish load on all slabs are 3.0 kN/m 2 and 1.5 kN/m 2 , respectively. The wall on this beam is 120 mm thick and 2.7 m high. Calculate design moment for span AB and support B after 22 % redistribution of moments. Design span BC and support B for flexure only. Draw the reinforcement details. Material- Concrete of grade M30, Fe 500 reinforcement.
Q5
- a)[13]

The unsupported length of column is 4.2m. The column is fixed at one end and hinged at the other. Show detailed design calculations and reinforcement details.
- b)[4]
Explain the role of longitudinal and transverse reinforcement of column.
OR- a)
Q6
- [17]
Design a bi-axial short column by limit state method to carry Ultimate load of 1200 kN. Ultimate moment of 100 kN-m about major axis bisecting the depth of column and 20 kN-m about minor axis bisecting the width of column. The unsupported length of column is 4.2m. The column is fixed at one end and hinged at the other. Use M25 grade of concrete and Fe 500 grade of steel. Show details of reinforcement in plan and sectional elevation.
Q7
- [18]
