Abstract:
Material hybrids, integral timber bridges: development, application and potential While some of the structures traditionally designed as covered wooden bridges from pre‐industrial times are still in use today, many of the wooden bridges built in recent decades often show moisture‐related damage after only a few years of service due to design‐related deficiencies. A prototype bridge design was developed by evaluating the most common causes of damage in timber bridges as part of an interdisciplinary research project aimed at developing robust, durable timber bridges. Based on this, the applicability of the “integral bridge” principle for the bridge material wood was examined. For this purpose, extensive theoretical investigations, load tests and long‐term durability tests were carried out on the structural element transition between the timber superstructure and the reinforced concrete substructure. The monolithic joint uses reinforcing steel bonded into the timber superstructure in a fiber‐parallel manner to transfer the bending tensile component. In the world's first realization of a total of three integral, covered timber bridges (Remstal near Stuttgart, 2019), carbon concrete was used as the bridge deck for the first time. The novel material is material‐efficient and durable. The following article explains the development of the new integral timber bridge type, explains its first implementation for the bridges of the Remstal Regional Garden Show 2019 and gives an outlook on the potential of novel material‐hybrid and integral bridges with timber as the load‐bearing material in combination or composite with steel and concrete.
