Hysteretic behavior of cambered surface steel tube damper: Theoretical and experimental research

Frontiers of Structural and Civil Engineering 2023, Volume 17, Issue 4, Pages 606-624 doi: 10.1007/s11709-023-0925-6

Abstract: The result shows that the CSTD yields a stable hysteretic response and affords excellent energy dissipationconducted to investigate the effects of the steel tube height, diameter, and thickness on the seismic performanceCompared with equal-stiffness design steel tube dampers, the CSTD exhibits better energy dissipation performance, more stable hysteretic response, and better uniformity in plastic deformation distributions.

Parametric computational study on butterfly-shaped hysteretic dampers

Ali Reza FARZAMPOUR, Matthew Roy EATHERTON

Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 5, Pages 1214-1226 doi: 10.1007/s11709-019-0550-6

Abstract: A parametric computational study is conducted to investigate the shear yielding, flexural yielding, and lateral torsional buckling limit states for butterfly-shaped links. After validating the accuracy of the finite element (FE) modeling approach against previous experiments, 112 computational models with different geometrical properties were constructed and analyzed including consideration of initial imperfections. The resulting yielding moment, corresponding critical shear force, the accumulation of plastic strains through the length of links as well as the amount of energy dissipated are investigated. The results indicate that as the shape of the butterfly-shaped links become too straight or conversely too narrow in the middle, peak accumulated plastic strains increase. The significant effect of plate thickness on the buckling limit state is examined in this study. Results show that overstrength for these links (peak force divided by yield force) is between 1.2 and 4.5, with straight links producing larger overstrength. Additionally, proportioning the links to delay buckling, and designing the links to yield in the flexural mode are shown to improve energy dissipation.

Experimental study of the restoring force mechanism in the self-centering beam (SCB)

Abhilasha MAURYA,Matthew R. EATHERTON

Frontiers of Structural and Civil Engineering 2016, Volume 10, Issue 3, Pages 272-282 doi: 10.1007/s11709-016-0346-x

Abstract: In the past, several self-centering (SC) seismic systems have been developed. However, examples of self-centering systems used in practice are limited due to unusual field construction practices, high initial cost premiums and deformation incompatibility with the gravity framing. A self centering beam moment frame (SCB-MF) has been developed that mitigates several of these issues while adding to the advantages of a typical SC system. The self-centering beam (SCB) is a shop-fabricated, self-contained structural component that when implemented in a moment resisting frame can bring a building back to plumb after an earthquake. This paper describes the SCB concepts and experimental program on five SCB specimens at two-third scale relative to a prototype building. Experimental results are presented including the global force-deformation behavior. The SCBs are shown to undergo 5%–6% story drift without any observable damage to the SCB body and columns. Strength equations developed for the SCB predict the moment capacity well, with a mean difference of 6% between experimental and predicted capacities. The behavior of the restoring force mechanism is described. The limit states that cause a loss in system's restoring force which lead to a decrease in the self-centering capacity of the SCB-MF, are presented.

Numerical study of the cyclic load behavior of AISI 316L stainless steel shear links for seismic fuse device

Ruipeng LI,Yunfeng ZHANG,Le-Wei TONG

Frontiers of Structural and Civil Engineering 2014, Volume 8, Issue 4, Pages 414-426 doi: 10.1007/s11709-014-0276-4

Abstract: This paper presents the results of nonlinear finite element analyses conducted on stainless steel shear links. Stainless steels are attractive materials for seismic fuse device especially for corrosion-aware environment such as coastal regions because they are highly corrosion resistant, have good ductility and toughness properties in combination with low maintenance requirements. This paper discusses the promising use of AISI 316L stainless steel for shear links as seismic fuse devices. Hysteresis behaviors of four stainless steel shear link specimens under reversed cyclic loading were examined to assess their ultimate strength, plastic rotation and failure modes. The nonlinear finite element analysis results show that shear links made of AISI 316L stainless steel exhibit a high level of ductility. However, it is also found that because of large over-strength ratio associated with its strain hardening process, mixed shear and flexural failure modes were observed in stainless steel shear links compared with conventional steel shear links with the same length ratio. This raises the issue that proper design requirements such as length ratio, element compactness and stiffener spacing need to be determined to ensure the full development of the overall plastic rotation of the stainless steel shear links.
