,Shenzhen 518054) Abstract: The structure plan, the seismic analysis and the seismic fortification measures of a project is described in the article
For the exceed-limit height, performance based seismic design was adopted, and the elastic analysis of multi-models using different programs and the static elastic-plastic analysis are given to ensure all the potential states of loading are enveloped
Some specific constructional measures are taken to ass
