The dynamic characteristics of long-span suspension bridges are complex. natural vibration frequency is changed with different structural parameters, and the sensitivity to parameters different. In order solve this problem, spatial model a bridge was established by using finite element software, first 20 periods, frequencies modes were analyzed calculated. accuracy obtained data verified throug...

Abstract Due to the limitations of railway route selection, some high-speed railways are inevitably built near or across fault zones. To study distribution rail-bridge interaction under different load history states suspension bridges three types near-fault pulse-type earthquakes, this paper takes China's longest bridge—Wufengshan Yangtze River Bridge as background and establishes a spatial mod...

In order to study the coupling vibration between a bridge and train under action of crosswind loads, dynamic interaction model wind–train–bridge system is established considering geometric nonlinear factors long-span suspension bridge. A calculation frame composed, corresponding computer program written. highway–railway scheme studied as an example. The linear responses simultaneous both loads ...

Abstract The suspension-type monorail (STM) is a new type of rail transit, currently developing rapidly in China. Due to its short construction duration and high terrain adaptability, STM can save large land resources. In particular, by supplementing the traffic systems medium-sized cities, contribute green tourism projects. However, no systematic study devoted transit system China, there still...

Modern pedestrian and suspension bridges are designed using industry standard packages, yet disastrous resonant vibrations are observed, necessitating multimillion dollar repairs. Recent examples include pedestrian-induced vibrations during the opening of the Solférino Bridge in Paris in 1999 and the increased bouncing of the Squibb Park Bridge in Brooklyn in 2014. The most prominent example of...

The application of GPS in bridge monitoring aims to determine accurately and precisely the response deck towers estimate main characteristics (amplitude modal frequencies). requirement is a high level accuracy availability fixed solutions, which ensure reliable operation result precise estimation bridge's response. However, derived time series can be contaminated by noise, due performance satel...
