The unit load method-some recent applications
暂无分享,去创建一个
The unit load method has been developed to achieve a pre-defined target configuration of section forces in cable-stayed bridges by optimizing the tensioning of the stay-cables. The method has been further developed into a versatile design tool that allows the definition of a target distribution of section forces or deflections in any structure. This paper briefly describes the method and provides three application examples where this method has been used: a cable stayed bridge, a concrete arch and the application of the method to the automated simulation of the incremental launching process of bridges.
