STRUCTURAL PERFORMANCE OF R/C L-SHAPED BEAM-COLUMN JOINTS USING 590N/mm² CLASS HIGH-STRENGTH REINFORCEMENT AND MECHANICAL ANCHORAGE

Abstract

Effective utilization of 590N/mm² class high-strength reinforcement is able to reduce number of footing beam reinforcements. However its validity is not verified by experiment. In this study, R/C L-shaped joint using 590 N/mm² class high-strength reinforcement and mechanical anchorage is tested. Consequently, the authors clarified that the proposed design formula can be applied for estimation ultimate strength of such joint as well as using normal-strength reinforcement.
