Safety investigations of an adaptive shell structure - Part 1: Basics and theory of the used methods

摘要

Until now, safety concepts of the construction industry do not consider the use of active components. However, such components are an essential part of ultra-lightweight structures. Therefore the special aspects of active components, such as safeguarding against failure and emergency operation mode, have to be included in the safety concept of ultra-lightweight structures. The present article describes the use of active components using the example of an adaptive shell structure. This shell structure was developed by research unit 981, a research unit funded by DFG (German Research Foundation). The article also proposes an adaptation of existing safety concepts by using approaches from other disciplines. Two well-known methods, such as fault probability and effect analysis (FMEA) and fault tree analysis (FTA), are presented. Part 1 of the paper (published in this issue) describes theoretical investigations on safety concepts, the adaptive shell structure and the design elements, developed in the framework of the research unit. Part 2 (to be published in an upcoming issue) will provide the results of a practical application of the methods described in the first part.
