Steel Connections Deterioration Coefficient Introduction for Post-Earthquake Fire Analysis

This paper follows the results of an experimental testing programme on steel beam-to-column end-plate connections on scale 1:1, realized in 2014. After a seismic movement, connections are the important parts of a structure that may carry permanent damage. This effect is not taken into consideration by today's advanced models for fire analysis like Vulcan, Safir and other. In the first part, the deduction of the deterioration coefficient is done. In the second part the examples of fire and post-earthquake fire analysis by applying the coefficient are done. The conclusions are in terms of difference in fire resistance of the structure for the above mentioned cases.
