Question: Assigned: 0 2 / 1 2 / 2 0 2 4 Due: 0 2 / 2 2 / 2 0 2 4 A steel column

Assigned: 02/12/2024 Due: 02/22/2024 A steel column made of A572 Grade 50 steel with the length 12ft and cross section w10x49 has two different boundary conditions: Case 1: fixed-pinned in xz plane, fixed-pinned in yz plane; Case 2: fixed-pinned in xz plane, fixed-pinned from top and bottom & pinned from mid point in yz plane. Please ensure to keep translation 3 free at the top node to allow buckling. Each student has different cross section as shown in the table below. For each boundary condition: a. Find the Euler buckling load with SAP2000; b. Find the Euler buckling load with hand calculation; c. Compare SAP2000 and hand calculation results, and discuss the reasons for differences; d. Calculate the design strength of the column using the column curve and compare with the Euler buckling load. ( Need hand calculation solution PLEASE )
