Seismic isolation effect of a new type of friction pendulum bearing in high-speed railway girder bridge

Biao Wei et al.

Summary: Residual displacement exists in traditional friction pendulum bearings (FPB) during earthquakes, which hinders their self-resetting ability. To address this, a new type of FPB called double concave friction pendulum with spring (DCFPS) is proposed. The restoring force model and hysteresis characteristics of the theoretical DCFPS are derived, and the seismic isolation effect of high-speed railway simply supported girder bridges (HRSB) equipped with the DCFPS is evaluated. Optimal spring parameters for the DCFPS are determined based on efficiency coefficient and optimal order methods. The research demonstrates that the DCFPS exhibits superior self-reset performance, with an S-shaped hysteresis curve. The stiffness of the DCFPS gradually increases with swing displacement, enhancing the overall stiffness of the structure. Installation of DCFPS in HRSB reduces girder displacement and residual displacement of the bearings. The recommended optimal stiffness and initial tension of the spring for the exemplified bridges are 3000 kN/m and 9 kN, respectively. This research offers a feasible solution for reducing maximum displacement and residual displacement in bearings during earthquakes.

Y. B. Yang et al.

Summary: A theoretical framework is proposed for detecting damages in the constituents of track-bridge systems by analyzing the vehicle-rail contact response. The framework includes the modeling of rail and bridge, derivation of closed-form solutions, and adoption of the instantaneous amplitude squared (IAS) as the damage index. Numerical validation confirms the reliability of the technique, and several factors affecting the detection results are identified.

Investigation of equal strength mild steel tenons as displacement restraining devices for long-span railway arch bridges

Biao Wei et al.

Summary: In this study, Equal Strength Mild Steel Tenons (ESMSTs) were developed as a displacement restraining device for long-span railway arch bridges. The performance of ESMSTs was evaluated through theoretical derivation, pseudo-static experiments, and numerical simulation. The results from a case study show that ESMSTs can effectively reduce the response of long-span railway arch bridges and exhibit good fatigue performance.

Effects of horizontal ground motion incident angle on the seismic risk assessment of a high-speed railway continuous bridge

Biao Wei et al.

Summary: This study investigates the effects of horizontal ground motion incident angle on a high-speed railway continuous bridge. The research found that longitudinal waves only cause seismic responses in the longitudinal direction, while waves in other directions can cause coupling responses in both longitudinal and transverse directions. The seismic damage of the sliding layer and CA mortar layer under transverse waves should receive more attention in seismic design.

Stochastic Transverse Earthquake-Induced Damage Track Irregularity Spectrum Considering the Uncertainty of Track-Bridge System

Yulin Feng et al.

Summary: The study proposed the track irregularity spectrum of LCBT-bridge systems for high-speed railway and investigated the damage laws of residual deformation of track-bridge systems after earthquake actions. By comparing the results obtained from IDCR and the fitting formula, it was found that tracks experienced significant high-frequency irregularities after earthquakes, which could be roughly divided into high-, medium-, and low-frequency wavebands leading to the application of a three-segment power function for the fitting of the track irregularity spectrum after earthquake actions.

Errors of structural seismic responses caused by frequency filtering based on seismic wave synthesis

Biao Wei et al.

Summary: This study examines the impact of filtering on seismic analysis errors by synthesizing artificial seismic waves. In a pure friction system, maximum acceleration remains unaffected by filtering, while the error in maximum relative displacement can be as high as 60%, decreasing with higher friction coefficients. The friction coefficient corresponding to a smaller structural seismic response in a spring-friction system turns out to be the most unfavorable for filtering errors, requiring greater attention during shake table tests.

Effect of seismic isolation on random seismic response of High-Speed railway bridge based on probability density evolution method

Haiyan Li et al.

Summary: This study evaluated the effect of seismic isolation on the random seismic response characteristics of a track-bridge system using a three-dimensional detailed nonlinear dynamic model. It was found that isolation bearings can reduce the response of the track structure and piers, but increase the response of the bearings. The change in equivalent radius of the isolation bearings has no significant influence on the random response of piers and track structures, but does affect the bearing response to some extent.

Summary: The study found that the rail, track plate, and base plate all bear large longitudinal forces and their stress envelope curves are antisymmetric. Broken track plates result in a sharp decrease in track plate stress and an extreme increase in rail stress and base plate stress near the gap. Broken base plates result in a sharp decrease in base plate stress and an extreme increase in rail stress and track plate stress near the gap.
