A W21 3 68 of A992 steel is used as a simply supported beam with a span length of 50 feet. The only load in addition to the beam weight is a uniform live load. If lateral support is provided at 10-foot intervals, what is the maximum service live load, in kipsyft, that can be supported? a. Use LRFD. b. Use ASD.
The beam in the figure carries a uniform load of 20 kN/m including its own weight, a concentrated load of 400 kN at 2.4 m from the left support and another concentrated load at 280 kNat 1.2 m from right end. The beam is laterally unsupported except at the two vertical ends. The beam is to be made of W 16 x 77. Use AISC Specifications for A36 steel Fy= 248.69 MPa. a. Determine the maximum bending moment of the beam. b. Determine the maximum or actual flexural stress of the beam. c. Determine the allowable flexural stress of the beam. d. Is it safe to use the said steel as beam? Why?
a cantilever beam is 280mm by 500 mmand is reinforced with 4-20mm diameter bars. determine if the 2.50 m long beam is adequate to carry uniform load 15 kn/m and a concentrated load at the cantilever end. Use f'c =21 Mpa, Fy= 275 mpa. Neglect weight of beam. Use n= 9
