Select the lightest designated W14x section (A992) for the load condition given below assuming the member is fully braced against lateral torsional buckling and no holes:
Pu = 400 kips (tension) Mux = 300 kip-ft Muy = 0 kip-ft
Make use of AISC-15 Table 6-2 but verify selection using more detailed calculations, tables and beam charts.

5) Compression combined with bending - design AW-section beam-column member is to be used in a braced frame, and must support factored LRFD loads of Pu 600k and moments Mux = 330 k*ft (these loads were derived through use of a rigorous 2nd-order analysis and include notional loads). The member is 18ft long and totally unbraced with respect to both flexural buckling (for compression) and lateral-torsional buckling (for flexure). Choose...

Design the lightest available W14 (A992) tension member by the 2016 AISC LRFD for a truss that will carry service DL = 100 kips and service LL = 320 kips. The member is 30 ft. long. The flanges will be bolted to the connection plates (A36) with -in bolts so that four bolts will appear on the cross-section Assume there are at least three bolts per line, standard holes, and the connection is adequate. Hint: Consider all applicable limit states.

The single-story unbraced frame shown below is subjected to dead load, roof live load, and wind load Figure 1 shows the results of a first-order analysis relative to the columns of the frame. The axial load and end moment (also equal to the maximum moment in the column) are given separately for the different load cases (i.e., dead load, roof live load, and lateral wind load). All vertical loads are symmetrically placed and contribute only to the Mnt moments (i.e.,...
