## **CE-601 (GS)** **Total No. of Questions: 8]** **[Total No. of Printed Pages : 4** **Roll No.** **CE-601 (GS)** **B.Tech., VI Semester** **Examination, May 2022** **Grading System (GS)** **Structural Design and Drawing (RCC-I)** **Time: Three Hours** **Maximum Marks : 70** **Note:** - Attempt any five questions. - All questions carry equal marks. - In case of any doubt or dispute the English version question should be treated as final. **1.** a) Briefly explain the principles of limit state. b) Define the following: - Characteristics load - Characteristics strength - Partial safety factor **2.** a) Design a R.C. beam to carry a load of 8 kN/m inclusive of its own weight on an effective span of 7 m keep the breadth to be 2/3rd of the effective depth. The permissible stresses in the concrete and steel are not to exceed than 6 N/mm² and 140 N/mm². Take m = 18. b) A T-beam of flange width of 1600 mm, Flange thickness 150mm, width of rib is 350 mm has an effective depth of 600 mm, the beam is reinforced with 6 bars of 20 mm diameter. Determine the ultimate moment of resistance. Use M25 concrete and Fe415 steel. **3.** Design a reinforced concrete slab for a room of clear dimension 6m x 5m. The slab is supported on walls of width 350 mm. The slab is carrying a live load of 6 kN/m² and floor finish is 1.5 kN/m². Use M25 concrete and Fe415 steel. The corners of the slab are held down. Sketch the layout of the reinforcement. **4.** Design an isolated square footing for a column 450mm × 450 mm reinforced with 8.25 mm diameter bars carrying a service load of 2000 kN. the bearing capacity of the soil is 250 kN/ m² at a depth of 1.2 m below ground. the footing is restricted to 2 m in one direction. Assume M20 grade concrete and Fe415 steel for footing, M25 grade concrete and Fe415 steel for column. Draw to scale: - Longitudinal section showing the reinforcement details. - The plan showing the reinforcement details. **5.** Design the stairs for a public building, supported on wall on one side and stringer beam on the other side. The horizontal span of stairs is 1.4 m. The risers are 120 mm and treads of 300 mm. Use M15 mix. **6.** a) Design a doubly reinforced beam of section 240×500mm to carry a bending moment of 80 kN-m. Assume clear cover at top a bottom as 30 mm and take m=18. Adopt working stress method. Assume the permissible stressed in the concrete and steel are not to exceed 5 N/mm² and 140 N/mm². b) A rectangular beam is 200 mm wide and 400 mm deep up to the center of reinforcement. With the 3-16mm dia of Fe415 steel. Find the ultimate uniformly distributed load which the beam can carry safely over a span of 5 m. Take M20 concrete. **7.** Design a short circular column of 6 m to carry an axial load of 250 kN if both ends of the column are fully restrained using - Lateral ties - Helical steel **8.** a) Write down the design step with formulation of two-way slab with all necessary checks. b) Explain the different types of footing with neat sketches. **PTO**
