ABSTRACT
The article describes interdisciplinary and comprehensive diagnostic tests of final bridge inspection and acceptance proposed for a soil – steel bridge made of corrugated sheets, being the European span length record holder (25.74 m). As an effect of an original concept a detailed and precise information about the structure response was collected. The load test design was based on the nonlinear numerical simulations performed by means of FEM. The in-situ measurements were done with aid of: inductive sensors, optical total station, terrestrial laser scanner. The results produced by terrestrial laser scanning were used to build a precise image of structure deformation in 3D space during the tests. The precision of laser mapping was additionally significantly increased by means of image tracing (vectorization) and calibration of results through parallel verification of the collected data with the values coming from optic total station and inductive sensors. Thus, new quality in measurements is introduced.
