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.

本文是作者在大型火力试验中进行的后续试验，该试验是在侧向荷载作用下无被动防火保护（PFP）的钢加劲板结构坍塌（Paik JK，Ryu MG，He KH，Lee DH，Lee SY，Park DK，Thomase G.，2020年。进行横向修补载荷下钢加劲板结构坍塌的全面耐火测试（第1部分）–无被动防火保护，船舶海上结构doi：10.1080 / 17445302.2020.1764705。测试结构代表最大测试尺寸和最大容量，符合测试设施的1900 TEU集装箱船的钢板面板。本文的目的是通过实验研究PFP的应用对钢加强板结构火灾塌陷的影响。以此目的，测试结构的两个横向框架（主要强度构件）由作为防火材料的金属陶瓷绝缘。在由液化石油气燃烧的熔炉中进行了燃烧测试。从火灾开始到测试结构完全坍塌，在不连续的时间间隔内监视结构的坍塌。通过与未经防火保护的结构的测试结果进行比较，研究了防火横向框架对结构塌陷的影响。
