N2 - Prestressed grouted sleeve connection is a competitive tubular steel jointing system due to its high performance in structural behaviuor and fabrication. It is found that the temperature distribution is one of the key factors affecting the load carrying capacity of this innovative connection. Temperature developments in fire and outdoor environment are predicted by FEM in this paper. The heat transfer by convection and radiation between atmosphere and the surface of the connections is considered in the analysis. The temperature distributions are presented for connections subjected to real car park fires and extreme outdoor environment. It is found that there are great temperature gradients existing within connection in fires, which will counteract the prestress developed in the connection. However, the temperature gradient can be ignored in the connections subjected to outdoor environment.
