Development of a wooden traffic sign bridge TTS - Bridge

Project background

Through the long-term binding of CO2 emissions and the substitution effects, building with wood can building with wood has been proven to be a key technology for combating global warming (Churkina et al. (Churkina et al. 2020). The strengthening the innovative power of the Bavarian economy in this area offers the opportunity, together with other timber construction countries, to play a strong role in building with wood as an active and effective contribution to climate protection but requires constant further development to expand and strengthen this position.

In particular traffic sign bridges made of wood as a green model for traffic the general public the efficiency of wood as a building material can be of wood as a building material can be impressively demonstrated to the general public.

Project objective

As part of the small-scale project, the project partners are working closely cooperation to develop an alternative timber engineering construction to the traffic sign gantries made of steel or aluminum that have been in use for decades. In the long term, traffic sign gantries made of wood should lead to a transformation from primary energy-intensive building materials to the use of sustainable and regionally produced constructions in infrastructure buildings.

The ongoing development process in timber construction offers the Bavarian timber construction landscape outstanding opportunities to increase increase the competitiveness and general acceptance of timber construction among the general public.

Project procedure

The project processing is divided into 6 work packages (WP), whereby project management and project management and literature research/basic research are not declared as a separate WP.

WP 1: Structural design

WP 2: Investigations into structural wood protection

WP 3: Structural detailing

WP 4: Implementation of monitoring systems

WP 5: Preparation Prototype construction

Innovation

There is still no traffic sign bridge in Germany traffic sign gantry made primarily from wood. This project is is therefore a step towards increasing the use of the renewable raw material wood in the previously previously neglected area of infrastructure construction.

Innovatively developed composite cross-sections (e.g. glulam hybrid beams made of larch or robinia and spruce as well as on the structural wood protection, as well as detailed designs and covers coverings) should meet the requirements of the road maintenance company in terms of performance, maintenance intensity and durability.

The adapted cross-section selection is supported by the identification of suitable data acquisition systems for climatic and material-inherent environmental and boundary boundary conditions. These data acquisition systems form the basis for the in-depth development of improved and more efficient constructions as well as for an estimation of the possible service life, e.g. according to the dose-response model according to Brischke C et al. (2019).
