Design a rectangular tied column for flexure in a reinforced concrete frame is subjected to the following loading scenarios: a. PD=200 kips, MD = 200 k-ft, PL = 100 kips, ML = 400 k-ft

The beam shown below is subjected to a uniform live load, ωL = 1k/ft. In addition, the beam must resist a superimposed dead load, ωD.S = 0.8k/ft as well as its self-weight. The concrete strength is 6,000 psi and the steel is Grade 60. The beam is not in contact with the ground or exposed to weather (hint: cover). Calculate the nominal and design shear strengths of the beam section. Is the beam shear design adequate? If so, redesign the beam to make the design more economical. If not, redesign the beam for shear to ensure the design is adequate per ACI 318-19 standards. . The beam shown below is subjected to a uniform live load, ωL = 1k/ft. In addition, the beam must resist a superimposed dead load, ωD.S = 0.8k/ft as well as its self-weight. The concrete strength is 6,000 psi and the steel is Grade 60.

a) Write and explain one advantage and onedisadvantage of using intermediate stiffeners in plate girders. b) If a plate girder design was initially determined to require intermediate stiffeners, but one optedtonot use them, how else could the plate girder be designed to achieve the same shaer capacity.  c) A w-shepe beam is bent in bi-axial bending. All loading passes through its shear center. Please explain why the flexural  strenght about its weak axis is the fullplastic moment capacity regardless of Lb

The service load bending moments on a beam are 128 kip-ft for dead load and 107 kip-ft for live load. The beam is 12 in. wide, f'c is 3000 psi and fy is 60 ksi. Determine Mu. Mt. p. R. the depth of the beam and the As of tensile reinforcing required. How many no. 8 bars or No. 10 bars would have the required As?
