The objective of this study is to investigate the feasibility of placing the standard ISO (International Standard Organization) shipping container into stackable units and to determine an economical strengthening solution for this purpose. An ISO shipping container is a box shape steel structure specially designed for transporting goods and products. The standard container is 20ft long and has a cross section of approximately 8ft×8ft (height × width), internal volume of 32m3 and carries a maximum gross weight of 30×103kg. ISO shipping containers offer many advantages for storage of goods and materials as compared to the conventional storage facilities. These include significantly lower cost, accessibility and easy transportation, low site preparation costs and considerably higher capacity. However, the standard ISO containers are essentially not designed for carrying loads in stackable form. Many issues such as lack of material strength, local buckling and global collapse may occur when the stackable container is subjected to seismic, and wind loads. An extensive structural analysis will be performed in this study to analyse the structural properties of ISO shipping containers and evaluate the possibility of developing a strengthening plan which transforms the ISO shipping container into a stackable containerized system. The scope of the study is limited to standard 20ft shipping container which will be analysed in empty, half-full and full condition subjected to seismic and wind loads. The response of ISO container structure will be studied using finite element method. A strengthening plan that can be customized according to the specific site features such as seismicity, wind load and soil property is expected to be developed following the feasibility studies. This collaborative research study between Ryerson University and Storstac Inc. (Industrial partner company) is expected to continue as a long term research project through this NSERC Engage proposal.

这项研究的目的是调查将标准ISO(国际标准组织)运输集装箱放入可堆叠单元的可行性，并为此目的确定一种经济的加固解决方案。ISO集装箱是专门为运输货物和产品而设计的箱形钢结构。标准集装箱长20英尺，横截面约8英尺×8英尺(高×宽)，内部体积为32立方米，最大毛重为30×103公斤。与传统的存储设施相比，ISO航运集装箱在存储货物和材料方面具有许多优势。这些因素包括成本低得多，交通便利，场地准备费用低，容量大得多。然而，标准的ISO集装箱基本上不是为以堆叠形式运输货物而设计的。材料强度不足、局部屈曲、整体变形等诸多问题 当可堆叠的集装箱受到地震和风荷载时，可能会发生坍塌。本研究将进行广泛的结构分析，以分析ISO航运集装箱的结构特性，并评估制定加固计划的可能性，将ISO航运集装箱转变为可堆叠的集装箱化系统。研究范围仅限于标准的20英尺集装箱，将在地震和风荷载作用下分析空的、半满的和满的状态。采用有限元方法对ISO集装箱结构的响应进行研究。在可行性研究之后，预计将制定一项加固计划，该计划可以根据特定的场地特征，如地震活动、风荷载和土壤性质来定制。 Ryerson大学和Storstac Inc.(工业合作伙伴公司)之间的这项合作研究预计将通过NSERC Engage提案作为长期研究项目继续进行。
