Computer Aided Deflection Control in Bridge Design
Australian Journal of Structural Engineering, 2002During the construction of bridges, significant displacements can be introduced into the structural system and are often compensated for with a pre-camber. The calculation of the exact shape of such a pre-camber is often a complicated and time-consuming task. In this paper, a system is introduced which allows the automatic computation of pre-cambers to

Bridge deck deflection: importance of early shrinkage
IABSE Reports, 2017<p>The construction of the viaduct over the A9 highway, a semi-integral prestressed concrete bridge with a total span of 351.60 m, was accompanied by uncertainties about the importance of long- term effects on the deck deformations. To clarify these, deformation measurements have been carried out using optical fibers, which turned out to be a ...

Separation of Bridge Deflection Signals Based on ICA
Advanced Materials Research, 2011In order to reject environmental factor effect from long-span bridge deflection signal, this document introduced the basic theory of independent component analysis (ICA) and applied FastICA algorithm to separate background engineering simulation signal, which was based on using vector-dimension-augmenting technique to process the signal after adopting ...
