Use A992 steel and select a W12 shape for axially loaded column as shown below to meet the following requirements: The length is 23 feet, both ends are pinned, and there is bracing in the weak direction at a point 13 feet from the top. The service dead load is 95 kips, and the service live load is 220 kips. Note: Use Table C.8 (Textbook) (Ans. W12 x 53) Answer is given. Please show the process of solving this and use semi-neat handwritten Thank you.
STRENGTH OF MATERIALS (Please write the complete solutions and FBD. Answer in 3 decimal places. No long written explanation needed.) The compound axial member shown consists of a 20-mm-diameter solid aluminum (E= 70GPa) segment 1, a 24-mm-diameter solid aluminum segment 2, and a 16-mm-diameter solid steel (E = 200 GPa) segment 3. Compute the change in length of the compound axial member.
Question 6 of 6 Fill in the blanks: Determine the design moment capacity of the beam with given properties below. bf = 400mm bw = 350mm tf = 120mm d = 370mm d' = 100mm fc' 34.5 MPa fy = 420 MPa As = 8- 28mm bars USE NSCP 2015, Mu = KN-m
The compression member shown is made of HE300B section. If Fy is equal to 320 MPa:a) Check the section for local buckling. b) Determine the maximum compressive service load that can be supported if the live load is twice as large as the dead load.
The W36 x 135 beam shown carries service loads shown (excluding weight). It has been decided to add a 10-meter steel column at point B to eliminate excessive deflection. If the column being added is fixed at the bottom and pinned at the top, design the column that can withstand as support (Use a recommended value for K. Evaluate using LRFD and ASD). a. Use WT18 section b. Use W36 section c. Using the section at (b), determine the dimension of the base plate if the foundation dimension will be 1500mm x 1500mm.
