Abstract:The common analysis methods and design process of out-of-code tall building structure were briefly described and summarized. Several main aspects were discussed, such as the main criteria of out-of-code tall building structure, seismic performance target settings, analysis process and structural strengthening and optimizing measures. By taking an out-of-code tall building structure as an example, the main points of its seismic performance analysis were summarized and sorted out. The project had certain typicality, and its analysis process could be used as a reference for similar out-of-code projects.
