Abstract

New beam-to-column connection is proposed for large elasticity to prevent damage under large eartquake and for reuse in the future. This connection can be made by employing super-high-strength steel (SHSS) with yield points of 800N/mm2 and super-high-tension bolt (SHTB) with split tee joiner. To verify its structural behavior, tensile and cruciform type beam-to-column connection specimens were tested and analyzed with an FEM. Tests and analytical results confirmed that the connection method is feasible as new reusable structures keeping elastic under large earthquake. However, the increase of strength for split tee and beam-to-column connection panel is still needed for further improvement.
