摘要：

The aim of this work is the design of the steel and concrete composite column subjected to fire considering material and geometrical nonlinearity. The paper presents the detailed analysis of the structural fire resistance in accordance with the Eurocode requirements. On the base of the nonlinear analysis using ANSYS software, the fire resistance of two types of columns - a reinforced concrete column and a steel and concrete composite column - has been investigated. The load of column section is considered alternatively. The Drucker-Prager yield function for the concrete, and Von Mises function for steel, have been taken. The theory of large deformations is regarded in geometrical nonlinearity. The FEM model is made from the solid (SOLID65) and shell (SHELL181) elements. (C) 2017 Published by Elsevier Ltd.
