Shipping containers are increasingly adapted for modern modular construction of both permanent and mobile low-cost civilian-use structures, with the diversity and interchangeability of their uses suggesting the need for container-based modular structures to conform to standard fire safety requirements, notably insulation and integrity. Multi-storey structures in city centres consisting entirely of modified shipping containers, or shipping containers fitted into structural frames, are becoming more commonplace. Full-scale fire tests are generally rather expensive and can be complemented with systematic numerical studies of fire resistance times offered by a range of passive protection configurations and thermal transport properties. Noting that standardised fire resistance ratings have three components (structural, insulation, integrity), this study specifically considers fire resistance times offered by passive fire protection configurations, by performing a series of time-dependent finite element heat transfer analyses of passively protected side panel configurations. A set of reference curves with which to determine insulation resistance times in the context of the ISO 834–1 standard fire curve is presented, specifically for use in the rational fire safety design of modular structures constructed from shipping containers. Negligible literature is currently available on fire resistance ratings of shipping container structures.

海运集装箱越来越适用于永久性和移动低成本民用结构的现代模块化结构，其用途的多样性和互换性表明需要基于集装箱的模块化结构符合标准防火安全要求，特别是绝缘和正直。市中心的多层结构完全由改装的集装箱或安装在结构框架中的集装箱组成，正变得越来越普遍。全面的防火测试通常相当昂贵，并且可以通过一系列被动保护配置和热传输特性提供的耐火时间的系统数值研究来补充。注意到标准化的耐火等级具有三个组成部分（结构、绝缘、完整性），本研究通过对被动保护侧板配置进行一系列瞬态有限元传热分析，特别考虑了被动防火配置提供的耐火时间。提供了一组参考曲线，用于在 ISO 834-1 标准防火曲线的背景下确定绝缘电阻时间，专门用于由运输集装箱建造的模块化结构的合理防火安全设计。目前关于航运集装箱结构的耐火等级的文献可忽略不计。提供了一组参考曲线，用于在 ISO 834-1 标准防火曲线的背景下确定绝缘电阻时间，专门用于由运输集装箱建造的模块化结构的合理防火安全设计。目前关于航运集装箱结构的耐火等级的文献可忽略不计。提供了一组参考曲线，用于在 ISO 834-1 标准防火曲线的背景下确定绝缘电阻时间，专门用于由运输集装箱建造的模块化结构的合理防火安全设计。目前关于航运集装箱结构的耐火等级的文献可忽略不计。
