Adaptive load-bearing structures are expected to be an important part of future construction projects. Based on lightweight construction, engineering structures could be developed and implemented in an even more resource-efficient and multifaceted way by means of adaptive systems. Design, planning, and implementation of adaptive structures is multifaceted and combines different fields (civil engineering, mechanical engineering, computer science, electrical engineering, materials science, etc.), so that interdisciplinary collaboration between different disciplines will be essential. The goals of this collaboration would be to find answers to the civil engineering problems (and the related ecological and social issues) of our time. Adaptive structural systems offer a fundamental and important approach to addressing present problems such as climate change, resource scarcity, pollution, and constant population growth. The demand for sustainability, efficiency, and recyclability is an important consideration for our future built environment. There is a clear shift in the construction industry where sustainability, above all, is the driving factor of many decisions in the design process. Future investigations of dynamic influences and the development of new design concepts should provide the answer of how and where exactly forces act inside systems and how these systems can be turned into adaptive structures. In this paper I will give a basic overview about adaptive load-bearing structures. In the first part I will present some basic information and a short literature review. After this, I will show some results of my investigations of a two-spring system and stiffness adaption through variable springs.
