Abstract

Abstract

The influence of temperature and edge distance on the shear performance of nine high-strength aluminum alloy plate bolted connections was studied through low-temperature monotonic tensile tests. The results showed that low temperatures did not significantly affect the failure mode of specimens. When the edge distance increased from 1.0d₀ to 1.5d₀ and 2.0d₀， the failure mode changed from net cross-section failure to a mixed failure of end tearing and transverse tearing； the ultimate bearing capacity of the specimen was basically not affected by low temperatures. However， when the edge distance increased from 1.0d₀ to 1.5d₀， the ultimate bearing capacity of the specimen increased significantly， by about 100%. The experimental results were compared with the calculation results of domestic and international standards. It was found that the American standard can better predict the ultimate bearing capacity of the specimens， while the calculation results of the Chinese and European standards are more conservative when the edge distance is not less than 1.5d₀.
