ABSTRACT

The aim of this paper is to present a fire test database on the collapse of a full-scale steel stiffened plate structure without passive fire protection under lateral patch loading. Steel plate panels of an as-built 1900 TEU containership in compliance with test facility in a maximum size and capacity were considered as a reference structure, with principal dimensions of 7 m long and 4.8 m wide fitted with two transverse frames and seven longitudinal stiffeners. Lateral patch loading was applied using two loading actuators at the centre of each transverse frame. A fire test was conducted in a furnace fuelled by liquefied petroleum gas, where the maximum gas cloud temperature inside the furnace was increased up to 800°C during testing. Time history of the lateral deformations of the test structure was measured with the focus on a critical period of time until the structure reached the ultimate limit state (or collapse) after the fires started. Details of the test database are documented, which will be useful for validating computational models for structural failure analysis in fires.

摘要

本文的目的是提供一个火灾测试数据库，用于在横向补片载荷下没有被动防火的全尺寸钢加劲板结构的倒塌。参照测试设施建造的1900 TEU集装箱船建造的钢板面板被视为参考结构，其主要尺寸为长7 m和宽4.8 m，配有两个横向框架和七个纵向加劲肋。使用每个横向框架中心的两个加载执行器进行横向补丁加载。在以液化石油气为燃料的炉子中进行了燃烧测试，在测试过程中，炉子内部的最高气体云温度提高到800°C。着眼于火灾开始后直到结构达到极限状态（或坍塌）的关键时间段，测量了测试结构的横向变形的时程。测试数据库的详细信息已记录在案，这对于验证火灾中结构破坏分析的计算模型将非常有用。
