Theoretical analysis of mechanical property of concrete filled steel tubular column after fire

Rang Yan-ya

Abstract

Based upon analysis of the constitutive relation of steel and concrete at elevated temperature the-curvilinear relationship of core-concrete at elevated temperature is obtained by numerical simulation.Parametric analysis visualized the main factors influencing the residual bearing capacity of concrete filled steel tubular column.In the end,simplified calculation formula of axial compression elastic ratio and axial compression bearing capacity are obtained.
