Study of Temperature Action of Reinforced Concrete Component at Elevated High Temperature

Based on the governing equations of thermal conduct, its finite element forms for transient temperature yields have been derived.Forthermore, the approximate formula for calculating the temperatures and the temperature internal forces of a nonsteady temperature field is deduced. By comparing and analying the test data with the calculated value,it is proved that the calculated method adopted in the paper is correct and valid. The conclusion can be applied valuably to engineering designs.
