Study on the Fire Resistance Performance of Panel Type Seismic Isolation Member Having Hollow Layer

Part1. Fire Resistance Test

Abstract

For fire-resistant coatings for seismic isolators with large hollow layers, fire resistant performance tests were carried out with specifications without residual displacement and with fire-resistant reinforcement of the joints for residual displacement of 70 mm. As a result, it was confirmed that the joint reinforcement functioned effectively when residual displacement occurred, since the same fire resistance performance was maintained even with specifications with residual displacement.
