Study On The Mechanical Performance Of Exposed Column Base

Column foot in the steel plays an important role, it is the main structure of the upper and the lower steel base connected to a key node. Mechanical properties of steel, pedestal and base connection stiffness are closely related. Foot steel column connection stiffness actually ranged between rigid and semi-rigid articulated state, and in the engineering design, the term is often simplified as rigid or articulated two limiting states.Flexural bearing capacity and stiffness in this paper exposed column base node, focuses on the study of stiffened plate height and thickness, bolt diameter, plate thickness, axial compression ratio and other parameters on the H section and rectangular steel pipe column of different size of the stress performance impact.
