An efficient method for analyzing the nonlinear aerostatic stability of long-span bridges using a modal formulation is proposed. First, simplified linear version defined as modal-based approach introduced, which evaluates bridge displacements properties and speeds up assessment critical velocity by applying root-finding algorithm. Then, this scheme further developed to identify instability limi...

Bridge vortex-induced vibration (VIV) refers to the vertical resonance phenomenon that occurs in a bridge when pulsating wind passes over it and causes vortices detach. In recent years, VIV events have been observed numerous long-span bridges, leading fatigue damage structure posing risks driving safety. The advancement of technologies such as structural health monitoring (SHM), machine learnin...

tables of maximum bending moment, shear force and support rections for simple bridges with span lengths ranging from 2m to 250m are presented.loadings are selected according to the specification given by the highways and transportation ministry of iran. the procedure of using the tables is shown by means of an example.

Corrugated Soil-Steel bridges have been used as drainage structures and underpasses in the ongoing Southern Highway project. Because the Soil-Steel bridges are novel to Sri Lankan context and the catastrophic bridge failure at Poddala, 2009 led to a controversy about the suitability and the stability of SoilSteel bridges. The structure safety against crushing failure of the corrugated steel arc...

The frequently conventional assumption that bridge temperature is uniformly distributed on long-span bridges could lead to uncertainty when analyzing effects. This study investigated the surface of steel box girders a suspension bridge, emphasizing distribution characteristics in longitudinal (spanwise) direction. girder was monitored using long-term structural health monitoring system (SHMS). ...

The traditional method for calculating the buffeting response of long-span bridges follows strip assumption, and is carried out by identifying aerodynamic parameters through sectional model force or pressure measurement wind tunnel tests. However, there has been no report on predicting based vibration test. In recent years, author proposed a method, integrated transfer function, theoretical ful...
