Question

 

kindly answer all 3 parts. all are part of same section..

8. HSS 10 x 8 x1/4 with Fy-50 ksi is selected to be used as a compression member with KL=10ft. Determine compressive strength of the member. Can you use buckling strength equations to determine its compressive strength, ØPn? 9. If the HSS 10 x 8 x1/4 in the previous problem is made with steel with E = 29,000 ksi and Fy = 36 ksi. Which elements of the cross section will cause local instability? 10. What elements in a W section under negative moment are subject to local buckling? How do you verify if this failure is the limiting state?
