A beam has dimensions of b = 14 in., h = 22 in., and d = 19.5 in. and is reinforced with 3 No. 8 bars. The concrete strength is 9,100 psi, and the yield strength of the reinforcement is 60,000 psi. Assuming the reinforcement has yielded, determine the tensile force T in the reinforcement.

Determine As,min for the following beam given that f’c = 6,750 psi and fy = 60,000 psi.

A beam has dimensions of b = 16 in., h = 24 in., and d = 21.5 in. and is reinforced with 5 No. 5 bars. The concrete strength is 7,900 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the nominal moment capacity, Mn, of the beam.

Use the MWFRS Envelope Procedure in ASCE 7-10 Chapter 28, Part 1 to answer this question. Assume that the building meets the conditions described therein. You have been tasked with designing an enclosed building. The mean roof height is 25 ft, and the roof angle is 20 degrees. The basic wind speed provided by the local building authority is 135 mph. Assume that exposure category C is applicable and that the building is not located on a hill or an escarpment. Determine the velocity pressure exposure coefficient, Kh.

Determine β1 given that f’c = 10,000 psi.

A simply supported beam with dimensions of b = 10 in., h = 28 in., d = 25.5 in., and L = 19 ft supports a uniform service (unfactored) dead load consisting of its own weight plus 1.0 kips/ft and a uniform service (unfactored) live load of 0.9 kips/ft. The concrete is normal-weight concrete. Determine the moment due to the factored loads, Mu.      

A beam has dimensions of b = 18 in., h = 30 in., and d = 27.5 in. and is reinforced with 5 No. 6 bars. The concrete strength is 2,800 psi, and the yield strength of the reinforcement is 60,000 psi. Assuming the reinforcement has yielded, determine the tensile force T in the reinforcement.

An experimental test of the hypothesis to explain the origin of the first organic compounds on Earth might include all of the following sequential steps, except for

A simply supported beam with dimensions of b = 16 in., h = 24 in., d = 21.5 in., and L = 21 ft supports a uniform service (unfactored) dead load consisting of its own weight plus 1.0 kips/ft and a uniform service (unfactored) live load of 0.8 kips/ft. The concrete is normal-weight concrete. Determine the moment due to the factored loads, Mu.
