摘要:This article deals with the analysis of applied radii in built architecture. This basic evaluation is part of a DFG (largest German research funding organization) research project ‘Basics to develop adaptive formwork systems for free-formed concrete building parts’. It serves to pre-configure adaptive formwork surfaces. The article describes the changes in modern architecture, from rectangular box to free-formed ‘blobs’ in terms of the geometry and the resulting issues of costs and manufacturing process.
