Resumen

In this paper the thermal analysis of the push out test of steel – concrete channel connections at elevated temperatures is carried out. The study takes into account numeric results generated by the program SuperTempcalc for two alternatives: protected and unprotected beams. Temperatures are proposed to be considered in determining the reduction factors of resistance and the impact of these results in determining the strength of the connection is evaluated. Finally, a simplified method for calculating the resistance of the connection is proposed, which considers defined temperatures in the concrete by the thermal analysis and is consistent with the formulations for calculating the resistance of channel connections at room temperature and with the current formulation for stud connections at elevated temperatures provided by international codes.
