Mechanical properties impact analysis of simply supported steel beam with torsional system under uniform load

Abstract

Abstract: In order to study the mechanical properties of simply supported steel beam with torsional system in the span under uniform load, the double variant stationary value theory of total potential energy was used to derive the correlation calculation formulas between critical uniform load of steel beam and torsion rigidity coefficient of torsional system. At the same time, the ANSYS finite element model is established to perform the buckling model analysis of simply supported steel beam with different torsion rigidity coefficients in the span. The theoretical calculation results and finite element analysis results both show that with the increase of the torsion rigidity coefficient, the critical uniform load of simply supported steel beam is improved effectively.

Key words: torsional system, uniform load, mechanical property, stationary value theory of total potential energy, finite element model
