![]() A new approach for assessing the dimensional accuracy and structural performance of spatial structure elements, using three dimensional (3D) laser scanning, has been shown in. In TLS automatic inspection system, enabling detection and measurement of damage together with the verification of the quality and durability of surface repairs, as required by industry standards, is presented. In situ, field tests and measurements are commonly utilized for the purpose of non-destructive testing. Therefore, recent achievements in this field are shown below. In this article, we deal with non-destructive testing issues related to: detailed, automated, high-accuracy geodetic measurements, especially using terrestrial laser scanning (TLS) determination of structural response of a bridge structural identification (St-Id) processes and structural health monitoring (SHM). A lot of review papers have been written that gather knowledge about non-destructive testing of different structures, see for example. Because of that, great attention is focused on understanding of the structures response, enabling appropriate failure prevention, determination of real properties of the built-in material, identification and detection of damage, and failure mechanisms or monitoring of structure health (SHM). Consequently, failures and damages of the aforesaid objects occur. Sometimes these conditions are not properly identified during their design or, basically, could not have been predicted because of some accidental circumstances that emerge at the site. Therefore, such a combination of testing methods can be used in non-destructive diagnostics of structures and is an interesting alternative for the standard approach, in which the measurements are done in limited number of points.Įngineering, mechanical, aerospace, offshore structures, etc., or their parts, elements, or connections are subjected to various and complex loading conditions during their life cycle. Good correspondence between in situ values and FEM estimations was achieved. Thus, new quality in measurements is introduced. These have higher accuracy and therefore can be used as reference. The accuracy of laser mapping was significantly increased using the information coming from total station and inductive sensors. ![]() The results produced by terrestrial laser scanning were used to build a precise image of structure deformation in 3D space during the tests. In situ measurements were done with the aid of: inductive sensors, optical total station, and terrestrial laser scanner. Load test design was based on numerical simulations performed by means of finite element method (FEM). Periodic diagnostics of bridge deformations was done one year after it was built. As an effect of an original concept a detailed and precise information about the structure short-term response was collected. The article describes interdisciplinary and comprehensive non-destructive 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).
