Abstract: In this dissertation a comparison between measured static data from field testing and computational results from finite element software has been illustrated to investigate the conformity between these two series stress increments. Shenzhen Stock Exchange new headquarters (SSE) will be taken as a paradigm. This dissertation is composed of three parts: Part one is to introduce the background of the research briefly and at the same time some review of structural health monitoring system used in civil infrastructure for static monitoring purpose will be represented. Part two is to introduce the methodology of research and conduct a study on SSE as the testbed. Part three is to suggest some fields where deserve to be expanded for further study. Also some approaches have been proposed for improvement. Part one consists of the first two chapters. Chapter one is used to introduce the background of research and its objectives. And chapter two is to list some applications of structural health monitoring system for bridges and buildings under constructions for static monitoring purpose. Part two is the key part of the dissertation and it includes from chapter three to chapter five. Chapter three will show the methodology of this research and chapter four has described the implementation of SHM on SSE in detail. Chapter five is to perform a case study to make a comparison between measured stress increments from field testing and computational counterpart from finite element software SAP2000. A discussion will be conducted to analyze the conformity of these two series data. Part three is made up of chapter 6. In this part research direction of further study will be proposed and some relevant methods will be put forward.
