Question: Question 1 ( 3 0 pts ) : The wall of a building is composed of braced W 4 6 0 6 8 steel columns

Question 1(30 pts):
The wall of a building is composed of braced W46068 steel columns connected rigidly to a concrete foundation as shown above. Each column has a height of 5m. The steel has a Young's modulus of E=200GPa and yield strength y=350MPa.
a) For buckling about its strong axis (x-x, what are the support conditions at each end and what is the effective length?
b) For buckling about its weak axis (y-y), what are the support conditions at each end what is the effective length?
c) What is the critical load P able to be sustained by the column shown above?
