Methodology for linking business processes undertaken during bridge load testing with the specification of required information according to OpenBIM standards

Correct process modelling is crucial for the implementation of BIM technology. Considering the interest of public procurement, the use of open standards supports the transparency of spending public money on construction projects. The aim of this paper is to model the flow of information at the stage of bridge load testing in order to properly use BIM technology for bridges. The authors present a concept known from software engineering - design pattern – a general, reusable solution for a commonly occurring problem within a given context, this time applied in infrastructure design.

Preparation, Installation and Signal Processing of Strain Gauges in Bridge Load Testing

Practical approach of strain gauges using is introduced. The use of strain gauges and signal processing of measured data at static experimental load testing of a concrete beam are carried out. The ability of the strain gauge sensor to pick up the specific deformation / strain signals during loading is investigated. The Fast Fourier Transformation (FFT) is applied to obtain the signal in frequency domain and reverse FFT to transform the processed signal back to time domain. The measurements are confirmed with some inductive transducers and total station. This approach is tested on 2.7 m long concrete beam in laboratory. A practical use of strain gauges with bridge constructions under complex inspection is described.
