摘要本文是作者早期文章Paik等人[2020 a.循环轴向压缩载荷下钢加筋板结构的全尺寸倒塌试验，Structures，https：//doi.org/10.1016/j.istruc.2020.05.026]。本文的目的是提供一个测试数据的极限压缩强度特性的全尺寸钢加筋板结构在低温条件下，这可能是由于不必要的液化气体的释放。测试结构是在造船厂使用与当今造船业完全相同的焊接技术制造的。实验结果表明，该结构在室温下完全不同于典型的破坏模式，而是由脆性断裂触发而达到极限状态。详细的测试数据库的文件，因为它们可以用来验证计算模型的结构耐撞性分析，涉及在低温条件下的脆性断裂。
ABSTRACT This paper is a sequel to the authors’ earlier article Paik et al. [2020a. Full-scale collapse testing of a steel stiffened plate structure under cyclic axial-compressive loading, Structures, https://doi.org/10.1016/j.istruc.2020.05.026]. The aim of the paper was to present a test data on the ultimate compressive strength characteristics of a full-scale steel stiffened plate structure at cryogenic condition which may be due to unwanted release of liquefied gases. The test structure was fabricated in a shipyard using exactly the same welding technology as used in today’s shipbuilding industry. It is observed that the test structure reaches the ultimate limit states triggered by brittle fracture, which is totally different from typical collapse modes at room temperature. Details of the test database are documented as they can be used to validate computational models for the structural crashworthiness analysis involving brittle fracture at cryogenic condition.
