Long term deflections of Paudèze Bridges

IABSE Reports, 2017
<p>The Paudèze bridges are two parallel bridges, each with a total length of around 400 m and a maximal span of 104 m. They were built using the balanced cantilever method between 1971 and 1974. After construction, a continuous increase in the deck deflections was observed.

Beam Deflection in Bridges Designed for Continuity

Journal of the Structural Division, 1957
Formula for deflection at any point, for continuous beam bridges where beams are of constant moment of inertia and constant modulus of elasticity; application may also be made for variable moment of inertia; formula applies to any number of continuous spans.

Analysis of Bridge Deflection Based on Time Series

Applied Mechanics and Materials, 2011
The bridge health monitoring system can collect large amounts of data, but it lacks the trend analysis of monitoring data. This article introduced the method of Time series analysis into the analysis of bridge monitoring data, and adopted ARIMA model in time series analysis of monitoring data, used the least square method for parameter estimation ...

A Generalized Deflection Theory for Suspension Bridges

Transactions of the American Society of Civil Engineers, 1935
AN IMPROVED AND EXTENDED DEFLECTION THEORY FOR SUSPENSION BRIDGES IS PRESENTED IN THIS PAPER. THE THEORY IS GENERALIZED TO INCLUDE STRUCTURES OF ANY NUMBER OF SPANS, CONTINUOUS OR NON-CONTINUOUS, SYMMETRICAL OR UNSYMMETRICAL, AND WITH OR WITHOUT TIE CABLES.

Deflections of prestressed concrete bridges in Japan

Magazine of Concrete Research, 1972
Synopsis This paper summarizes and discusses measurements made of the deflections in service of four prestressed concrete bridges in Japan. The bridges, of long-span and central-hinge type, were constructed by the cantilever method. The paper discusses a simplified formula for calculating the deflection occurring after hinges have been joined.

High Frequency Deflection Monitoring of Bridges by GPS

Journal of Global Positioning Systems, 2004
The use of GPS for the deflection and deformation monitoring of structures has been under investigation for a number of years. Previous work has shown that GPS not only measures the magnitude of the deflection of the structure, but also it is able to measure the frequency of the movement.

Corrected Deflection Theory of Suspension Bridges

Transactions of the American Society of Civil Engineers, 1960
Theory presented considers several effects neglected in previous theories such as those due to shear force and to elongation of cable; only theory, and not practical method of solution, is dealt with.

Full-Bridge Deflected Shape Synchronous Measurement in Bridge Loading Test

Journal of Bridge Engineering, 2011
A loading test can provide valuable insight into the behavior and fundamental characteristics of an existing or new bridge. The full-bridge deflected shape in long-span bridges is an important parameter that evaluates the safety state of a structure.

Deflection Control of Prestressed Box Girder Bridges

Journal of Bridge Engineering, 2014
The models for prediction of creep in codes and design guides are mainly based on tests in which the load is sustained for a number of years, rarely exceeding 10; however, most models predict that creep reaches its extreme after approximately 30 years.
