A New Hybrid Friction Damper (HFD) for Dual-Level Performance of Steel Structures

Seismic Response and Economic Study of New Light Steel-Wood-Plastic Structure in Rural Yunnan, China

“…To simplify this part of the calculation, the total loss ratios of the seismic-isolated models and the seismic-resistant model are taken as 2.7% and 18.1%, respectively, in this paper [31]. And the loss ratios of seismic-damped models are taken as 5.9% [31].…”

“…To simplify this part of the calculation, the total loss ratios of the seismic-isolated models and the seismic-resistant model are taken as 2.7% and 18.1%, respectively, in this paper [31]. And the loss ratios of seismic-damped models are taken as 5.9% [31]. Assuming that the total value of the building's interior property is equal to the total cost of the building structure itself, the seismicresistant model loss value is as follows: C L = C S × 18:1% = 8594:6$, and the postearthquake loss values for each structure in the seismic-isolated and seismic-damped systems are shown in Table 8 below.…”

“…Li et al [21,22] studied the stress-strain relationship of soil under repeated loads to provide data support for practical engineering. Natale et al [23,24] studied a PBEE-based method to quantify the payback time (PBT) of seismic retrofit solutions for existing RC buildings, based on the fact that the high installation costs of foundation isolation limit its widespread use in common designs; Li [25] applied different dampers to an engineering example for performance analysis; Wang [26] used three different support systems for a dynamic time analysis of the Songhua Bridge and concluded that the system equipped with dampers was more favourable for seismic resistance; Li and Zhou et al [27,28] introduced the composition and performance of friction pendulum and how to mitigate the seismic effect of building structures in engineering practice; Nakamura and Okada et al [29] verified the effectiveness of seismic isolation and reaction control methods by shaking table tests and seismic response analysis for three types of rubber bearings and three types of damping devices; Natale et al and Di Sarno et al [23,30] studied how highly damped rubber bearings mitigate the seismic effects of steel buildings in actual earthquakes; Shahbazi and Moaddab [31] illustrated the intrinsic relationship and the acceleration and displacement response spectra of displacement-dependent dissipators in structures, as well as the principles and practical applications of displacementdependent dissipators; Dong et al [32,33] studied the hysteretic force-deformation response of large dampers. Wen et al [34] research found that unsoaked rocks are the strongest.…”
