Continuous Monitoring of Masonry Arch Bridges to Evaluate the Scour Action

نویسندگان

چکیده

The shallow foundations that often characterizes multi-span masonry arch bridges are highly vulnerable to the soil settlements typically induced by riverbed scouring. Consequently, monitoring of scouring effects is paramount importance ensure safe operation these river bridges. Within a recent collaboration between Politecnico di Milano and Regione Lombardia, bridge has been selected exemplify quasi-static strategy capable detecting flood-induced scour. structure, built during second half 19th century, was subjected numerous strengthening interventions, especially on pier resting riverbed. installed heterogeneous sensor network consists tiltmeters (measuring rotation piers at skewback level), 1 weather station, hydrometer, echo-sounder. In addition, detection debris accumulation performed with cameras taking pictures from upstream side. After concise description structure Sesia River, paper focuses adopted measuring system results obtained in first months continuous monitoring.

A Parametric Study: Frame Analysis Method for Masonry Arch Bridges

The predictability of masonry arch bridges and their behaviour is widely considered doubtful due to the lack of knowledge about the conditions of a given masonry arch bridge. The assessment methods for masonry arch bridges are MEXE, ARCHIE, RING and Frame Analysis Method. The material properties of the masonry and fill material are extremely difficult to determine accurately. Consequently, it i...

Sensitivity Analysis and Parameter Identification on historical Masonry Arch Bridges

Close to reality computation of the serviceability and load-carrying capacity of old masonry arch bridges for rising live loads is a current problem. In Germany many of such roadand railway bridges exist. Some of the most important features for applicable numerical evaluation of masonry arch bridges are a realistic structural model (very often three dimensional models are necessary), the consid...

Deflection Measurement of Masonry Arch Bridges with Tall Piers: Case Study of Shahbazan Bridge

A common practice for detailed assessment of masonry bridges is to use recorded deflection signature of mid-span of such structures due to predefined loading schemes. However, measuring the deflection of bridges with tall piers or those situated over deep valleys introduces certain difficulties, since common deflection-meters require a reference point relative to which the measureme...

An Examination of Backing Effects on Ratings for Masonry Arch Bridges

Many single or multispan arch bridges are strengthened with the addition of some kind of structural support between adjacent arches of multispan or beside the arch barrel of a single span to increase the strength of the overall structure. It was traditionally formed by either placing loose rubble masonry blocks between the arches and beside the arches or using mortar or concrete to construct a ...
