The frame object axial and moment strengths are tested in this example.moment strengths are tested in this example. A continuous column is subjected to factored loads and moments
A continuous column is subjected to factored loads and moments C C f f= 2000 kN;= 2000 kN; M
M fx fx-top-top= 200 kN-m;= 200 kN-m; M M fx fx-bottom-bottom= 300 kN-m. This example was tested using the CSA= 300 kN-m. This example was tested using the CSA S16-09 steel frame design code. The design capacities are compared with S16-09 steel frame design code. The design capacities are compared with Handbook of Steel Construction (9
