“…A web-core sandwich panel GFRP bridge consists of a vacuum-infused ribbed sandwich panel that acts as a deck structure, as well as the main load carrying structure [18][19][20][21][22]. In its basic simply supported configuration, spans of 20 m are realistic although in other configurations, larger spans are achieved through e.g.…”

This paper reports experimental data for the dynamic properties (i.e. first fundamental flexural frequency, damping ratio, comfort class) of ten web-core sandwich panel FRP composite footbridges in Belgium, which contributes to the assessment of relevant input parameters for design and assessment of this promising bridge type, quickly gaining popularity in recent years. The data is gathered based on smartphone accelerometers, enabling easy, quick, affordable, and abundant measurements, while at the same time yielding reliable experimental values. Given the relatively short spans, the heel and excitation test methods are used, rather than the ambient vibration method. The tests indicate damping ratios of one to three percent, which are strongly dependent on the number of people on the bridge during the measurement. Additionally, comfort analysis tests with up to 58 people (0.5 P/m²) were conducted on five out of the ten bridges. The results indicate that the current design guidelines for pedestrian comfort analysis are overconservative and do not reflect the effect of pedestrian-induced damping, which is especially apparent for this bridge type given its very low modal mass and relatively low damping ratio.

“…Fibre reinforced polymers (FRP) or fibre polymer composites (FPC) show important potential for bridge construction [1][2][3][4][5][6][7][8][9]. For example, they are relatively stronger and lighter than classical building materials such as concrete and steel [10][11][12], they are more durable than timber and require less maintenance. Especially when looking at footbridges [13,14], this type of material can offer an added value.…”

In this work, structural design and manufacturing of sandwich composite floor for automobile was performed. The tensile and compression strength of specimen were investigated. Based on this, structural design of floor board was performed. The sandwich composite floor board are subject to payload. The maximum load was analyzed in consideration of the safety factor. The structural design and analysis were performed in consideration of applied load. The finite element analysis method was applied to investigate structural safety. The stress, displacement, and buckling analysis was carried out. Through the structural analysis, it was confirmed that the designed floor board structure is safety. Based on the result, the manufacturing of prototype was conducted. Finally, test and evaluation of composite floor board was performed.
