Abstract

This paper is a sequel to the authors’ article on a full-scale fire testing to collapse of a steel stiffened plate structure without passive fire protection (PFP) under lateral patch loading (Paik JK, Ryu MG, He KH, Lee DH, Lee SY, Park DK, Thomase G. 2020. Full-scale fire testing to collapse of steel stiffened plate structures under lateral patch loading (Part 1) – without passive fire protection. Ships Offshore Struc. doi:10.1080/17445302.2020.1764705). The test structure represents steel plate panels of a 1900 TEU containership in compliance with test facility in a maximum size and capacity. The aim of this paper is to experimentally examine the effects of PFP application on the fire collapse of steel stiffened plate structures. For this purpose, two transverse frames (primary strength members) of the test structure were insulated by cerawool which is a fire protection material. A fire test was conducted in a furnace burnt by liquefied petroleum gases. Structural collapse was monitored at discrete time intervals from when the fire started until the test structure entirely collapsed. The effect of fire-protected transverse frames on the structural collapse was investigated by comparison with test results on the structure that was unprotected from the fires.
