Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 1,   Pages 190-200 doi: 10.1007/s11709-018-0487-1

Abstract: Cumulative AE energy was also affected commensurately.Damage was quantified in terms of internal energy dissipation due to both matrix cracking and fiber pulloutThe results showed that fiber pullout was the dominant energy dissipation mechanism; however, the sumof the internal energy dissipation measured amounted to only 60% of the total energy dissipated by thedissipation.

Evaluation of a developed bypass viscous damper performance

Mahrad FAHIMINIA, Aydin SHISHEGARAN

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 3,   Pages 773-791 doi: 10.1007/s11709-020-0627-2

Abstract: In this study, the dynamic behavior of a developed bypass viscous damper is evaluated. Bypass viscous damper has a flexible hose as an external orifice through which the inside fluid transfer from one side to the other side of the inner piston. Accordingly, the viscosity coefficient of the damper can be adjusted using geometrical dimensions of the hose. Moreover, the external orifice acts as a thermal compensator and alleviates viscous heating of the damper. According to experimental results, Computational Fluid Dynamic (CFD) model, a numerical formula and the simplified Maxwell model are found and assessed; therefore, the verification of numerical and computational models are evaluated for simulating. Also, a simplified procedure is proposed to design structures with bypass viscous dampers. The design procedure is applied to design an 8-story hospital structure with bypass viscous dampers, and it is compared with the same structure, which is designed with concentric braces and without dampers. Nonlinear time history analyses revealed that the hospital with viscous damper experiences less structural inelastic demands and fewer story accelerations which mean fewer demands on nonstructural elements. Moreover, seismic behaviors of nonstructural masonry claddings are also compared in the cases of hospital structure with and without dampers.
