| Abstract: | In this paper,the temperature of steel connections in fire and finite element analysis are mainly investigated.In experiments,we do some tests about the temperature of the steel connections in the furnace designed by ourselves.We acquire the temperature-time curve.The experience formula is given to compute the temperature of steel connections.We also make analysis on the temperature of the steel connections.The results show that the experiments are close to the finite element analysis and the analysis is proved to be practicable and reliable.Then we discuss the regular pattern of the temperature to provide a basis for design. |
| Keywords: | fire experimental research temperature-time curve finite element connection |
