III B.Tech I Semester Regular Examinations, November 2007 STRUCTURAL ENGINEERING DESIGN AND DRAWING-I(RCC) (Civil Engineering) Time: 3 hours Max Marks: 80 Answer any ONE Question from PART-A and any THREE Questions from PART-B Note:Assume suitable data whenever necessary Use of IS codes & Structural Tables is permitted ????? PART-A(Marks:32)
1. Design a doubly reinforced section for a rectangular Beam at mid span having an e?ective span of 4m. The superimposed load is 40 kN/m and size of the Beam is limited to 250mm x 400mm overall. Adopt M20 grade concrete and Fe 415 grade steel. Draw to a suitable scale. (a) Longitudinal section showing reinforcement details. (b) Cross section of the Beam showing reinforcement details.
2. A square column of 400mm size is carrying a live load of 260 kN and dead load of 340 kN including self weight. The allowable net bearing capacity of the soil is 100kN/m2 and allowable width of the footing is 2m. Design an isolated footing with M20 concrete and Fe 415 grade of steel. Draw to scale: (a) Plan showing the reinforcement details (b) Sectional elevation of the footing. PART-B (Marks:16x3=48)
3. (a) Distinguish between static modulus and dynamic modulus of elasticity of concrete. (b) Why does the code limit the compressive strength of concrete in structural design to 0.67 fck and not fck.
4. (a) De?ne the term ‘partial safety factors’ as used in limit state design. Identify the various factors and state the values recommended in IS 456. (b) Compare ‘working stress method’ and ‘limit state’ design of R.C.C. structures. Explain the answer with suitable examples.
5. Determine the shear stress in a 250 X 500 mm rectangular section if the shear force is 20 kN and torsional moment is 10 kN.m at service loads. Asume M 20 mix and 0.75% tension reinforcement at an e?ective coverof 50 mm.
6. Design the reinforcement for a R.C.column 250mm x 400mm in cross section for the following data. Pu =1000KN; L=6M, lex = 4.m; leu =4.0 m; M20 and Fe 415. M ux =30KN-M at top and M ux =20KN-m at bottom; M uy =10KN-m at top and bottom, which is braced and bends into single curvature e?ective cover d1 =50mm.
7. Design a simply supported slab to rest on masonry walls for a live load of 4kN/m2 if the clear spam is 2.8m. Use M 20 grade of concrete and HYSD Bars.
