In addition, the behavior is affected by other characteristic phenomena at elevated temperatures such as explosive spalling or transient creep. The difficulty to develop a concrete model suitable for the anal-ysis of structures at high temperatures is also due to the severe Nettetbased on the models proposed by Lubliner et al.
