“…The aim of the investigation created by Siwowski et al [7] were static tests of the full-scale hybrid FRP/RC girder and to present testing results in terms of its general behavior, carrying capacity, failure modes and FEM model validation. The research program created by Chróścielewski and Wilde et al [8] was greatly expanded beyond the typical set of all-GFRP bridge acceptance tests. It was divided into two main parts: static -two ballast settings and dynamic pedestrian forcing, modal hammer and an exciter.…”

The dynamic behavior of lively footbridge is a complex problem. Recently there were numerous publications and recommendations related to the dynamic nature of footbridge. The complicated procedure which was set in a number of instructions and standards says nothing about actions aimed at avoiding critical frequency range in structure. In the paper, results of dynamic in-situ tests of cable-stayed all-GFRP (Glass Fiber Reinforced Polymer) footbridge are presented. Fiberline Footbridge, located in Kolding city in Denmark, was constructed in 1997 using 12 different pultruded profiles all made of GFRP material. The dynamic characteristics as well as vertical response of the tested footbridge under human excitation are given and discussed. Firstly, in order to estimate the dynamic properties of the footbridge, a series of free-decay responses under human jumping were conducted. The fundamental frequency of the analyzed structure was within a critical range. A methodology for footbridge classification with regard to their dynamic sensitivity was worked out and the correlation between the structure's properties and its dynamic response under pedestrian excitation was formulated. It was found that the analyzed footbridge fulfilled vibration comfort criteria elaborated by technical guide Sétra, however, more restricted acceleration limits suggested by Eurocode were not met.

“…During tests, a total of 216 various types of measurement points were used to identify the behavior of the structure. A laser scanning was performed on one side of the composite GFRP girder [8]. The novel idea of an all-composite structural system for road bridges has been proposed for the first time in Poland by Siwowski et al [9].…”

“…The implemented project [11][12][13] included a series of experimental, numerical and technological tests [14,15], which made it possible to monitor the entire process, from a preliminary concept to building a full-scale object. The finished footbridge was subjected to a series of static and dynamic tests [15,18] and technical monitoring [25] based on earlier gained experience [19][20][21][22][23][24].…”

The paper presents results of systematic tests of contraction and thermal expansion coefficients of materials based on polymer composites. The information on the above material properties is essential both at the design stage and during the use of finished products. Components for the samples were selected in such a way as to represent typical materials used for production of construction and moulding elements. The performed tests made it possible to monitor the analysed parameters at different stages of the technological process.

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.
