摘要：
This article aims at presenting and discussing the strategies used to identify the most representative modal parameters of a short span masonry railway bridge, estimated by performing vibration testing to validate and update the numerical models for the bridge structural analysis. The bridge behavior is simulated by a three-dimensional finite element model and the validation of the bridge updated material properties is also complemented on the basis of material testing results and observations taken from visual inspections.
