STRUCTURAL PERFORMANCE OF R/C EXTERIOR BEAM-COLUMN JOINTS USING CIRCULAR ANCHOR PLATE FOR DEFORMED REBAR OF 590N/mm2 AND 685N/mm2 STRENGTH

The ultimate strength of R/C exterior beam-column joints using several types of mechanical anchorage for deformed rebar can be calculated by the proposed design formula derived on the basis of past test results. However, structural performance of such joints using a typical mechanical anchorage and circular anchor plate is not verified by a comparative test. In this study, the authors experimentally clarify the ultimate strength and ductility of R/C exterior beam-column joints using circular anchor plate to compare with a typical mechanical anchorage for deformed rebar of 590N/mm2 and 685N/mm2 strength.
