A simply supported beam with dimensions of b = 10 in., h = 28 in., d = 25.5 in., and L = 17 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 = 24 in., and d = 21.5 in. and is reinforced with 2 No. 7 bars. The concrete strength is 3,100 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the compressive stress block is a = 1.518027 in. and the strain in the reinforcement is εs = 0.033116, determine the strength φMn for this beam. Assume the transverse reinforcement is not spirals.

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 20 ft, and the roof angle is 20 degrees. The basic wind speed provided by the local building authority is 115 mph. Assume that exposure category D is applicable and that the building is not located on a hill or an escarpment. Determine the velocity pressure, qh.

A beam has dimensions of b = 16 in., h = 26 in., and d = 23.5 in. and is reinforced with 3 No. 7 bars. The concrete strength is 7,600 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the nominal moment capacity, Mn, of the beam.

A patient is a 28 year old G3 P2, who is pregnant with their 3rd baby and is 30 weeks gestation. They have a history of gestational diabetes with their first two children, but was diet controlled during those pregnancies. They have been diagnosed with gestational diabetes again with this pregnancy and is now requiring insulin to manage their blood sugars. When providing education to the patient regarding risks of diabetes, which statement by the patient would indicate the need for further teaching?

A beam has dimensions of b = 16 in., h = 24 in., and d = 21.5 in. and is reinforced with 5 No. 7 bars. The concrete strength is 9,700 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the compressive stress block is a = 1.364463 in. and the strain in the reinforcement is εs = 0.027726, determine the strength φMn for this beam. Assume the transverse reinforcement is not spirals.
