2. Design Wide flange column section only of A992 steel to serve as a pinned- end main member column 30 ft long to carry an axial compression loads in a braced structure, based on AISC LRFD method. The dead load is 50 kips A992 13-0" and live load is 70 kips. The member has strong axis direction supported at 17ft height from the bottom of the column. Dead load is 20 kips and live load is 40 kips. Assume the...

Problem 3: Design of Steel Beam for Bending with Varying Unbraced Lengths Select the lightest A992 steel W-shape for the beam shown below using LRFD. Only consider design (neglect shear a bracing situations: a. Continuous lateral support of the compression flange b. Lateral support at beam ends and at the point of the concentrated load c. Lateral support only at beam ends PD = 10k PL-20k WD-3.33 k/ft w, = 6.67 k/ft 10' 20' 30'

2. The frame shown in the figure below is unbraced, and bending is about the x-axis of all members. All beams are W16 x 40. Column BC is supported in the weak direction (i.e 2 direction perpendicular to the plane of the frame) at mid height and it is assumed pinned at both ends in this direction (i.e. Ky=1) Assuming that all columns are rectangular HSS 14x6x5/8,...

Problem 5: Design of Idealized Compression Member A 20-ft long column is pinned at the bottom and fixed against rotation, but free to translate, at the top. It must support a service dead load of 110 kips and a service live load of 110 kips. a) Select the lightest W12 of A992 steel. Use the column load tables b) Select the lightest W18 of A992 steel. Use the trial-and-error process.

Homework Problem Set #2 A W10x22 used as a column under axial compression. Assume that it is unbraced unless specified otherwise. Use A36 steel. For each column length and end conditions given, calculate the design capacity, pePa (25 points) (a) L = 8 ft, pinned ends (b) L-8 ft, fixed ends (c) L = 16 ft, pinned ends (d) L = 16 ft, fixed ends (e) L- 16 ft, pinned ends, braced at the midspan in the weak axis direction.

Problem 2. Design and select an ASTM A992 (Fy" 50 ksi) W-shape column to carry an axial dead load of 140 kips and live lond of 420 kips. The column is 30 feet long, and is pinned top and bottom in both axes. In addition, the column is laterally braced about the y-y axis (local weak/minor axis of the section) and torsionally braced at the midpoint. Limit the column size to a nominal 14 in. shape, that is W14 shape...

2. (1.5 points) A 24-ft simple span that supports three (3) service concentrated live load of 20 kips each at quarter points is laterally unbraced except at its ends and the center line. If the maximum permissible center line deflection under service live load equal L/400, select the lightest Wsection of 50 ksi steel, considering moment, shear, and deflection. Neglect beanm weight. Use Cb-1.0.
