The city of Kouvola is about to realize a high quality, recreational route for pedestrians and cyclists. In order to improve the functional connections and the recreational activities on the Kymi riverfront approximately a dozen of wooden bridges in a variety of spans, most of them in the range of 6 to 10 m will be built. Even though they will have different structural configurations, they will create a “family” of bridges, sharing common design aspects.
This paper presents a novel approach for one of the above-mentioned, bridges: 6 m span and approximately 1 m in width, where fin-like stiffeners are utilized for three different purposes. Firstly, a set of non-continuous, vertical timber fins is stiffening the deck of a bridge. Secondly, the fins are form-defining elements for the planar or elastically bent and therefore arched deck. Thirdly, the fins will function as railings, seats, etc.
Numerical and experimental investigations are carried out in order to analyze the influence of several parameter on the structural behavior of the bridge. Among others (a) the position and orientation of the fins, (b) the overlapping distance between fins, and (c) the geometric characteristics of the fins and the deck are investigated.
Based on the results of the investigations an alternative design concept is introduced that combine aesthetic, sustainability and easiness of construction.
