  1. A 14ft long simply supported beam of A992 steel is laterally braced only at its ends. It has a uniformly distributed dead load of 2k/ft. and uniformly distributed live load of 3k/ft. Determine: Size based on bending.
    determine Factored loads, bending moment,
    Determine Allowable Bending Moment based on Lb
    compare actual to allowable
    check deflection with 5wL4/384EI
    Check Shear determine Maximum shear Vu compare to allowable .6FyAwCv

Expert Solution

i choosed a section with much higer z and I since if lb exceed lr again capacity reduces. so for a safer side i did so

comment for any doubt
