| Abstract: | The cold-formed procedures of cold-formed rectangular steel tube increase the yield point and tensile strength, at the same time the cold-formed procedures also decrease the ductile behavior,it analyzes the influence of cold-formed procedures on the connection of cold-formed rectangular steel-tube column and H-shaped beam. At the same time, using the software of ANSYS, this thesis compares and analyzes the yield load, ultimate load and deflection ductility of the connections of cold-formed rectangular tube-steel column and H-shaped beam, and the connection of welding box column and H-shaped beam, in order to research the influence of the cold-formed procedures on column-beam connections. |
