“…However, since the FEM model has to be able to predict localised failure modes, core was modelled with solid elements, based on similar research [5][6][7][8][9][10][11][22][23][24]. Due to significant thickness of MgO board the facings were discretised with solid elements as well.…”

Abstract. Sandwich panels are readily used in civil engineering due to their high strength to weight ratio and the ease and speed of assembly. The idea of a sandwich section is to combine thin and durable facings with a light-weight core and the choice of materials used allows obtaining the desired behaviour. Panels in consideration consist of MgO (magnesium oxide) board facings and expanded polystyrene core and are characterized by immunity to biological corrosion, a high thermal insulation and a relatively low impact on environment. Customizing the range of panels to meet market needs requires frequent size changes, leading to different failure modes, which are identified in a series of costly full-scale laboratory tests. A nonlinear numerical model was created with a use of a commercial ABAQUS code and a user-defined procedure, which is able to reproduce observed failure mechanisms; its parameters were established on the basis of small-scale tests and numerical experiments. The model was validated by a comparison with the results of the full-scale bending and compression tests. The results obtained were in satisfactory agreement with the test data.

“…Such desirable improvements, in comparison to traditional SIPs, make CSIPs a very attractive alternative with a broader field of applications [16][17][18][19][20][21]. Increased strength of this type of sandwich makes it a viable option even in bridge structures [22][23][24].…”

Abstract. The purpose of this article is to show the modern engineering, in which sustainability and taking care of ecology play a significant role. The authors are focused on FRP composite materials and their applications in civil engineering. Case studies showing renovation and design of new bridges with the use of FRP are presented and discussed to clarify benefits, which this solution provides. Main advantages of FRP materials in comparison with traditional ones, like concrete or steel are showed. The environmental impact of composites is described with respect to all life cycle of a product. Furthermore, some forms of waste management are covered. Last part of the paper refers to scientific description of the pedestrian bridge made of FRP, which was realized under the Fobridge research grant. The group of researchers headed by professor Chróścielewski from Gdansk University of Technology has developed a design solution of the pedestrian bridge manufactured in one production cycle. Moreover, the footbridge construction contains a significant share of a recyclable material commonly called PET. The article contains main characteristics of the structure and production process based on the resin infusion.

“…What is worth mentioning, the use of PET foam significantly improved environment-friendliness of the footbridge. The next step was to perform material testing to identify its mechanical characteristics and to execute simultaneously numerical and validation analyses (Chróścielewski et al 2017). The experimental research included tests on laminate coupons (see Fig.…”

Abstract. Application of GFRP composites in civil engineering is still not large but already noticeable. Advantages of this material, such as: low volume weight, relatively high stiffness and strength, well fatigue resistance, easiness in shaping, high material damping and high environmental resistance, make it attractive for bridge and in particular footbridge designers. It is estimated that nowadays in the world there are realized hundreds of bridges, the construction of which, whole or in part is made of GFRP. Most of them are small span structures. However, it is possible to find some interesting designs. The paper presents an overview of the most spectacular examples of footbridge structures, in which the GFRP materials plays a key role. The few examples are: Aberfeldy Footbridge in Scotland, the world's largest structure of this kind; Lleida Pedestrian Bridge, the longest arch bridge made out standard GFRP pultruded profiles or EXPO Footbridge in Lisbon, truss bridge of 30 m span length. The last example is the footbridge designed and constructed by polish consortium Fobridge. The footbridge, which arose as a result of scientific project was studied in a great details taking into account, among others: material testing, validation studies and load tests.
