Abstract
Testing methods of inspection of buckling-restrained braces is specified in many technical specifications, but the existing specifications do not clearly indicate the connection type used for the specimen. There are three main connection types of buckling-restrained braces applied in engineering. This paper has carried out a large number of tests, focusing on the influence of different connection types on the test results. For the welded joints specimen, typical test results of mechanical properties of buckling-restrained braces were obtained. For the bolted joints specimen, slippage is likely to occur during the test; for the pin joints specimen, misalignment is likely to occur during the test and they are not suitable for use. In order to ensure the normal operation of the test and the comparison of the test results, it is not necessary to simulate the connection types when the test of buckling-restrained braces is performed. No matter which connection type of the buckling-restrained braces is used in engineering, the unified connection type is recommended in the test. It is recommended to use the welded joints.
