1.Draw the moment diagram for the beam. EI is constant. Assume the support at A is fixed and B and C are rollers.
2.The latitude of a course is -195.61 feet and the departure is +572.53 feet. What is the azimuth and the length of the course respectively,
a. 108deg 51’ and 605.03 ft.
b. 109deg 44’ and 605.03 ft.
c. 161deg 09’ and 615.25 ft
d. 108deg 51’ and 615.25
3.Determine a set of a rectangular beam design values b,d and As that will be needed to support a factored bending moment Mu= 450 Kip-ft.
Use f'c= 4500 psi and fy= 40000 psi. Use beam width of approximately 0.6 times the effective depth.( b=0.6 d).
4.Design a one way slab to support a uniform live load of 300 psf. The beam is simply supported with a span of 20 ft. Use a reinforcement ration ( Ps) of 0.008 Use f'c=3000 psi and fy=60000 psi.
