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.

摘要

本文是作者较早的文章Paik等的续集。[2020a。循环轴向压缩载荷下钢加强板结构的全尺寸坍塌测试，《结构》，https：//doi.org/10.1016/j.istruc.2020.05.026]。本文的目的是提供有关在低温条件下全尺寸钢加劲板结构的极限抗压强度特性的测试数据，这可能是由于不希望的液化气体释放造成的。测试结构是使用与当今造船业完全相同的焊接技术在造船厂制造的。可以看出，测试结构达到了由脆性断裂触发的极限状态，这与室温下的典型坍塌模式完全不同。
