A nonlinear approach for the life-cycle cost (LCC) analysis is proposed. Computational procedure for the analysis of LCC for seismically isolated bridges in a region of low to moderate seismicity is established. To compute the failure probability of critical structural components, most probable failure modes for the structure-isolator system are defined as unseating failure of a superstructure,...

The active early warning system of ship–bridge collision avoidance is a hot topic in academic research; however, practical applications, false alarms and missing often occur. To deal with this problem, we propose an algorithm on risk that considers the ship’s dimension. First, establish cartesian coordinate system, then dimensions relationship between geometric position ship, pier, channel. com...

Based on the high-pile and high-pier bridge of Qianhuang Expressway, eigenvalue buckling analysis is carried out by establishing three-dimensional finite element models three different types types, corresponding structural nonlinear loads under initial pier deviations are calculated. The calculation results show that less than elastic loads. stability column continuous better simple supported b...

Abstract Scouring is a complex process dependent on several factors, and local scour more than general scour. This study was an attempt to predict round bridge piers based in the water stream. Three obstacle shapes were used – circular, round-nosed, elliptical as they are predominant hydraulic structures like piers. For each shape, depth measured around periphery for five gradually increasing d...

Based on a large span continuous rigid frame bridge in Chongqing of China, the main pier vertical displacement and deviation, the bridge deck alignment and the expansion joint deformation are analytically researched during operation. Firstly, the monitoring content and method of the large span continuous rigid frame bridge are clearly stated. Secondly, by finite element software Midas Civil, th...
