RISFatigue Damage in Railway Steel Bridges: Approach Based on a Dynamic Train-Bridge Coupled Model
Publisher: American Society of Civil Engineers
Abstract: This paper evaluates the fatigue stress and damage accumulation in steel railway bridges using a dynamic coupled train-bridge system model. The system consists of a spatial vehicle model, a three-dimensional (3D) bridge ...
Fatigue Reliability Assessment of Railway Bridges Based on Probabilistic Dynamic Analysis of a Coupled Train-Bridge System
Publisher: American Society of Civil Engineers
Abstract: This paper presents an approach to fatigue reliability assessment of railway bridges based on probabilistic dynamic analysis of a coupled train-bridge system. The fatigue loading from moving trains is investigated through ...

Case Study of Innovative Top-Down Construction Method with Channel-Type Excavation
Publisher: American Society of Civil Engineers
Abstract: Although the conventional top-down construction method is widely used in deep excavation, it has the drawback of low efficiency attributable to the long hauling distance and the possibility of the occurrence of excessive ...
A Drive-By Frequency Identification Method for Simply Supported Railway Bridges Using Dynamic Responses of Passing Two-Axle Vehicles
Publisher: ASCE
Abstract: A drive-by method is proposed to identify the modal frequencies of railway bridges from the dynamic responses of two-axle vehicles. The theoretical closed-form solution and frequency components of the vehicle response are ...
