EVALUATION OF YIELD STRENGTH IN ANGLE BRACE CONNECTION BASED ON STRESS DISTRIBUTION

This paper discusses an evaluation method of yield strength at the angle brace connection based on stress distribution. The monotonic tensile tests were conducted to clarify factors affecting the yield strength. As a result, yield strengths on brace connections were found to depend on connection length, the out-plane eccentricity and in-plane eccentricity. In addition, numerical analyses were carried out to investigate the effects of various parameters on the stress distribution in the yield strength of the connection. Finally, an evaluation model for the yield strength on angle brace connection based on stress distribution was proposed.
