EK188
The combined shortening effect due to creep, shrinkage and temperature reductions induces tensile stresses in the precast components. The stresses must be accounted for in the connection design by either […]
EK116
Reinforcement will retain about 50% of its normal strength after reaching about 550 degrees Celsius, while for pre-stressing tendons the corresponding temperature is only 400 degrees Celsius.
EK115
Although concrete has low thermal conductivity, and thus good resistance to temperature rise, the strength begins to drop significantly at temperatures above 300 degrees Celsius and it has a tendency […]

Typical curve showing the evolution of the temperature of concrete in a structural element:
EK59
Being a good conductor of heat, the steel will reach the same temperature as the fire surrounding it and transfer the heat away from the area to affect other remote […]
EK54
Cold worked steel members are more affected by increased temperature. Connections should be checked for thread stripping and general soundness. An approximate guide is that connections heated to 450 degrees […]
