Determine the necessary reinforcement for a T section that has a flange width b 40 in 1000 mm flange thickness
Determine the necessary reinforcement for a T-section that has a flange width b=40 in. (1000 mm), flange thickness t=4 in. (100 mm), and web width b𝑤 =10 in. (250 mm) to carry a factored moment of 545 K⋅ft (750 kN⋅m). Given: f′c = 3 ksi(20 MPa) and fy =60 ksi (400 MPa).
2. The two-span continuous beam shown in Fig. 4.17 is subjected to a uniform dead load of 2.6 K/ft (including its own weight) and a uniform live load of 3 K/ft. The reactions due to two different loadings are also shown. Calculate the maximum negative factored moment at the intermediate support B and the maximum positive factored moment within the span AB (at 0.42L from support A), design the critical section at B and D, and draw the reinforcement details for the entire beam ABC.
Given: L=20 ft, b=12 in., and h=24 in. Use d=18 in. for one row of bars and d=17 in. for two rows. Assume f′c = 4 ksi and fy =60 ksi.
