“…It is needed to load the bridge in such a way that the resulting effects, such as internal forces, displacements, and stresses are large enough. Namely the ratio between the measured and designed values should be greater than 75% and not exceed 100% [39][40][41][42][43][44][45][46][47][48].…”

The paper presents application of different sensors for the purpose of short and long term measurements, as well as a structural health monitoring (SHM) system to assess the behavior of a novel fiber reinforced plastics (FRP) composite footbridge. The aim is to present a thorough and concise description of these sensors networks and results gathered with their aid during in situ measurement of strains, displacements, and vibrations, as only a few works are available in this field. The bridge geometry, material solutions, and properties are described at first. Then the measurement devices composing the system and subsystems of sensors are elaborated on. Subsequently, the bridge research program is described and the results are shown and discussed. Finally, it is concluded that the use of selected sensors is helpful in assessment of the behavior of the novel structure, and moreover in validation of its numerical models. The collected data confirmed many assumptions made during the bridge design process and allowed us to accept it for exploitation.

The article presents acceptance load tests of a newly built extradosed MS-3 bridge located along the national road DK-16 near Ostróda (Poland). The structure features significant dimension in European reference scale. It is a new record holder in span length regarding this distinct bridge category. Its length ranges 206 m. Static and dynamic load tests were performed here. The program was extended by entire structural laser scanning and identification of natural vibration forms.

“…As these technologies are very effective and usually provide the optimal foundation of the structure, particularly important is the ability to estimate the extent of shocks as well as amplitudes of propagating vibrations. The field tests are the most important in monitoring process of the impact of the construction works [1][2][3][4][5][6][7][8]. They enable the in-situ measurement of propagating shocks.…”

This paper presents results obtained with the use of accelerometers during in-situ testing and its comparing with results from numerical simulations. Horizontal accelerations of propagating impulses caused by driving the prefabricated piles were recorded. Range of the quakes as well as amplitudes of longitudinal and transverse horizontal accelerations of propagating vibrations on the terrain surface were determined. The recorded results were used to calibrate the numerical model of the finite element method. The most important factor influencing the propagation of impacts is the phenomenon of damping of the propagating wave in the soil. The mechanism of damping proposed by Rayleigh was used in the analysis, which, when selecting the appropriate parameters of the model, is able to realistically simulate the observed phenomena. The soil, in which the propagation of impulses occurred, was described with the use of linear-elastic model. Modulus of deformation correspond to the values of small deformations, which occur during the wave propagation in the subsoil. The impulse giving vibrations was caused by the falling hammer on the driven pile. The axial symmetry of the border condition was used in the analyses. The results of numerical simulations were compared with the results of field measurements of accelerations at different distances from the source of vibration. A good consistency of acceleration amplitudes in the direction of vibration propagation was achieved and it depended on the distance from location of the driven pile. The obtained results will be used in the future to assess the extent of the impacts on the environment and values of acceleration on elements located in the vicinity of the structure.
