1. Design a rectangular reinforced concrete beam to resist service moments of 120 kNm from dead loads and 110 kNm from live loads. The beam dimension are (b x d) 0.25m x 0.6m. Assume fck = 25 N/mm2and fyk = 500 N/mm2.
1. Design a rectangular reinforced concrete beam to resist service moments of 120 kNm from dead loads and 110 kNm from live loads. The beam dimension are (b x d) 0.25m x 0.6m. Assume
fck = 25 N/mm2and fyk = 500 N/mm2.
2. Check the design from Q1.
3. A reinforced concrete beam is 0.25m x 0.450 m (b x d). The tension reinforcement provided is 2H25 (As = 982mm2). Determine the moment of resistance of the section if fck = 25 N/mm2 and fyk = 500 N/mm2.
4. By using the information from Q3, calculate the actual area of reinforcement required.
5. Design a rectangular reinforced concrete beam to resist service moments of 195 kNm from dead loads and 145 kNm from live loads. The beam dimension are (b x d) 250 x 500 mm. Assume fck = 30 N/mm2 and fyk = 500 N/mm2. The depth to compresssion reinforcement is 45mm.
