| Summary: | 碩士 === 國立臺灣大學 === 土木工程學研究所 === 87 === Five welded beam-to-column moment connections consist of reduced beam sections are cyclically tested. Key parameters include the amount of radius cut and the strength of the beam-column panel zone. Test results indicate that the average strain hardening ratio of the reduced beam section is 1.20. The total plastic rotation capacity of each specimen exceeds 0.04 radian. For strong panel zone joints, most of the plastic rotation concentrates in the reduced beam section. For weak panel zone joints, test results confirm that the amount of beam strength reductions can be reduced thereby delaying the initiation of the inelastic local buckling at the reduced beam section. Test results illustrate that properly proportioned and constructed moment connections employing the reduced beam section and the weak panel can possess excellent inelastic deformation capacity. The paper concludes with recommendations for the design of the reduced beam section and the weak panel in order to achieve well balanced inelastic deformations.
