The wall of a building is composed of braced W360 x 57 steel columns connected rigidly to a concrete foundation as shown above. Each column has a height of 4 m. The steel has a Young's modulus of E = 200 GPa and yield strength o, = 500 MPa. 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?

Question

The wall of a building is composed of braced W360 x 57 steel columns connected rigidly to a concrete foundation as shown above. Each column has a height of 4 m. The steel has a Young’s modulus of ? = 200 GPa and yield strength ?? = 500 MPa.
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?
