A 3.048 m long column (Fy = 483 MPa) carries an axial compression load of 5000 kN dead load. The column is braced at mid-height to strengthen the column in the weak direction. Use LRFD.  Which of the following most nearly gives the nominal compressive strength?   Show solution and drawings

When an open-ended square tube is placed vertically into a pool of water, the water rises 4 mm up inside of the tube. A) Determine the inner length of the square tube. A solid cylindrical rod is then placed vertically down the center of the open-ended square tube and the water rises an additional 4 mm up the tube. B) Determine the diameter of the solid rod that was inserted. 0.073 @ 20N m T C s = = o .

Please use the following labels in the image such as Va, Vbr, Vbl and etc. Show step by step solution for each. Thanks!

The single story building shown in Fig. 2 has an applied uniform load of 300 psf (0.3ksf) including the self weight of the beams and the girders. The roof has a 16 ft x 15 ft opening as shown.  1. Determine the axial loads on Columns C1 and C2 using reactions from the beams supported on the columns. 2. Determine the axial loads on Columns C1 and C2 using the concept of tributary areas.

A built-up beam section is formed by welding 2xL8x6x1 angles to the bottom flange of        W36x210 as shown in Fig. 1.  Determine the following section properties of the built-up cross section: a. Cross sectional area, A (in2) b. The location of the centroids CG-X and CG-Y id of the built up section from the bottom of angle ( this value is given, so you need to check that you get this value) c. Moments of  inertia  ICG-X (in4) and ICG-Y (in4) d. Section modulus Sx (bot) (in3) and Sx (top) (in3) e. Radius of gyration rx (in) and ry (in) f. Weight of the built up section, w (lb/ft) (use density of steel = 490 pcf) g. Surface area of the built-up section, S(ft2/ft)
