ABSTRACT
To quantify how partially seismic-damaged structures respond under PEF loading, a sequential methodology was introduced and employed, whereby numerous case studies (including steel and RC structures, both lowand high-rise) were investigated. The results of the investigations performed in the previous chapter showed that the PEF resistance of structures can be reduced, even by as much as half, when compared to their resistance to fire alone, i.e. fire prior to earthquake. In bare steel structures, steel materials are often extremely vulnerable to high temperature and can lose their strength and stiffness at a rapid rate. Drift value at different performance levels can also adversely influence the fire resistance, in such a way that the more a structure sustains drift, the greater will be the reduction in fire resistance.
