The present paper summarizes recent research on timber–concrete composite (TCC) systems exposed to fire conditions. Experimental work on these systems in fire conditions is not as extensive as in normal temperature conditions. Therefore, only a few types of TCC systems are covered herein. The secondary objective of this paper is to present the principles of existing simplified procedures for TCC systems in fire. These procedures were developed and/or validated with regard to available fire test data, and to discuss the possibilities for the development of new enhanced, simplified calculation methods. A summary is then presented of design recommendations based on previously discussed experiments. A short discussion follows on their further development, and the possibility of the recommendations being included in future versions of European standards. Design criteria for screwed connections are presented, while for notched and glued-in rod connections, further research is required.
