Development and validation tests of an assembly self-centering energy dissipation brace
https://orcid.org/0000-0001-9205-9533
Abstract This investigation develops and experimentally studies an assembly self-centering energy dissipation (ASCED) brace that consists of an energy dissipation device composed of friction pads, a self-centering device composed of disc springs, and bracing members. The ASCED brace has attractive assembly and adjustment abilities and uses simple mechanics. Cyclic test results of the energy dissipation device demonstrated that it had stable energy dissipation capability without deterioration of the friction pads or loosening of the high-strength bolts. A large-scale ASCED brace specimen was designed, fabricated, and tested under cyclic loadings, and the results verified the adjustability of the ASCED brace and confirmed the cooperation performance of the energy dissipation device and the self-centering device. Repeatable flag-shaped hysteretic responses and a smooth transition of stiffness between different stages were observed. These results demonstrated the favorable seismic performance of the brace. The residual deformation was negligible when the pre-pressed force of disc spring was greater than the friction force provided by the energy dissipation device.
Highlights Assembly self-centering bracing system is proposed and its mechanics are presented. Validation tests on energy dissipation device and brace specimen were conducted. ASCED brace exhibits flag-shaped response with large energy dissipation capability. ASCED brace can be adjusted over a wide range of strength levels.
