In Germany, there is a great need for renovation and new construction of motorway and railway bridges. Project C07 addresses this issue and investigates the potential of adaptive structures in bridge construction. This research project focuses on three adaptation targets, namely the retrospective adaptation of existing bridges to extend their service life, the adaptation of lightweight bridges with an unfavorable ratio of traffic load to dead load, also with the aim of extending their service life, and the adaptation of stiffness-dominated bridge structures to reduce deflections. In addition to the broad design approach for innovative adaptive bridges, the manipulation of the load-bearing and system behavior is pursued with a holistic approach in regards to the adaptation of deformations and vibrations.

在德国，高速公路和铁路桥梁的翻新和新建需求很大。项目C07解决了这一问题，并研究了自适应结构在桥梁施工中的潜力。本研究项目侧重于三个适应目标，即现有桥梁的追溯适应，以延长其使用寿命，适应轻型桥梁的交通荷载与恒载的不利比例，也以延长其使用寿命的目的，和适应刚度为主的桥梁结构，以减少挠度。除了创新自适应桥梁的广泛设计方法外，还采用整体方法对承载和系统行为进行控制，以适应变形和振动。
