Note Answer eny IS 456, IS 800, steel tables and scientific calcu14tor ate pennitted. Assume any mis$ing data suitetbly,
1. Find the moment carrying capacity of a singly reinforced concrete beam of 200 mm width and 400 mm effective depth. It is reinforced with 4 bars of 16 mm diameter.
Take Fe 415 steel and M 20 concrete for the beam
Write the advantages of using spiral shaped transverse reinforcement in RC columns 7
2. An RCC cantilever beam of 3 m span supports a distributed factored load of 120 kN/m. The beam has at uniform width of 300 mm, with overall
depth varying from 650 mm at the support to 400 mm at the free end. the beam is reinforced with 2 bars of 20 mm diameter on the bottom side and 5 bars at 28 mm diameter on the top side with effective cover of 50 mm. Design shear reinforcement for the beam. Use M 20 grade concrete and Fe 415 grade steel reinforcement. 14
3. Design a floor slab for an interior room, with clear dimension of 4.0 x 8.5 m for a building. The slab is assumed to be simply supported on 230 mm thick masonry walls. The floor loading consist of live load of 4.0 kN/m and 1.5 kN/m2 due to finish, partition, etc. Fe 415 steel and M 20 concrete are used for construction.
4. Explain why deflections in concrete structures are undesirable. What are the major factors that affect deflection Discuss briefly. 7
Discuss the behaviour of under-reinforced and over-reinforced concrete beams. 7
5. Calculate the design compressive load carrying capacity of a discontinuous strut having the centre-to-centre distance 2.5 m between the end connections. It consists of two ISA 70 x 70 x 6 mm angles connected to an 8 mm gusset plate. Consider the following cases 14
Connected to the same side of gusset plate.
Connected to both sides of gusset plate.
6. Write the steps of design of built-up steel columns provided with lacing flats. 7
Compare the merits and demerits of Reinforced concrete and steel construction. 7
7. Write short notes on any two of the following topics: 2x7=14
Limit States of Design
Importance of Transverse Reinforcement in Beams
Quality Control of Concrete
