Seismic effectiveness assessment of nylon lines for the protection of museum artifacts via shaking table tests.

Earthquakes pose a significant threat to museum artifacts, as they can lead to irreversible damage or even complete destruction. Nylon lines have been commonly used in museums to secure these invaluable treasures. However, the employ of nylon lines primarily relies on the subjective opinions of decision-makers and there is a lack of detailed research on their seismic effectiveness, leading to inadequate protection against seismic events. The aim of this study is to provide valuable insights into enhancing the seismic safety of museum artifacts and assess the effectiveness of nylon lines in reducing seismic risk. In order to thoroughly investigate the negative impact of floor acceleration amplification on the artifact's seismic safety, a full-size reinforced concrete framework was built specifically for conducting shaking table test. The findings suggest that the use of nylon lines can be an effective means of protecting museum artifacts during earthquakes. Numerical simulation was utilized to further investigate the major factors affecting the seismic performance of nylon lines, including the diameter, the quantity, the tying angle, and the pretension applied. Based on the test and numerical results, recommendations were provided for the selection and installation of nylon lines to enhance their seismic performance.
