4. Use A992 steel and select the lightest W12-shape for the beam-column shown in the figure below. The member is part of a braced frame, and the axial load and bending moment are based on service loads consisting of 30% dead load and 70% live load (the end shears are not shown) Bending is about the strong axis, and K= Ky=1.0. The frame analysis was performed consistent with...

Problem 4: Determine if the 87/4 x 15-inch cross section for the column shown below is sufficient to resist the axial loads given below using ASD methods. The column is manufactured using axial combination 2 and is a DF glulam. The column is a pinned-pinned end column (i.e., K = 1.0), the moisture content is 11%, and the temperature is in the normal range for occupancy. D = 20 k L = 40 k L = 22 ft L =...

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.,...
