A simply supported beam of 8.5 m span is to carry a uniform ultimate load of 60 kN/m. The beam dimensions are 250 x 450mm. The longitudinal reinforcements provided are 6H20 for tension and 3H16 for compression. Design the shear reinforcement using vertical links. Assume fck= 25 N/mm² and fyk = 500 N/mm ².

1. For the cantilever beam shown below the required area of steel is 2.12 in?. 3 #8 bars are used. The end of each bar includes a standard 90 degree hook that is terminated at 2.5 in. from the outside face of the supporting column. Is the anchorage length sufficient to fully develop the tensile strength of each of the steel bars?Assumptios are as follows: fe = 4000 psi ; fy = 60000 psi ; uncoated coated bars ; light weight concrete; Sufficient stirrups provided 1.93 3#8 3#8 |2,5" 12" 12"

A rectangular concrete beam is 12 in. wide and has an effective depth (d) of 18 in. Compression steel is located 2.5 in. from the compression face of the beam and is two No. 8 bars. Calculate the design moment capacity of the beam, for f'c = 4,000 psi and fy = 60,000 psi. Solve for the following tension reinforcement amounts: a b C Three No. 10 bars in one layer Four No. 10 bars in two layers (Two No. 10 bars in each layer) Six No. 9 bars in two layers (Three No. 9 bars in each layer)

A 62.6-kN vertical load P is applied at the corner of the square cross section of the steel compression member AB, which is free at its top A and fixed at its base B. Knowing that for the grade of steel used oy=345 MPa and E= 200 GPa, and using the allowable-stress method, determine the smallest allowable dimension d. B D 1.5 m The smallest allowable dimension dis mm.
