Integrated Design and Application of Structural Health Monitoring Software System of Shanghai Tower

This paper introduces the prototype software system for structural health monitoring (SHM) of Shanghai Tower. The core conception of this prototype system is the integrated framework, composed of the data acquisition layer, the data publication layer and the data application layer. According to the characteristics of the hardware arrangement of SHM system of Shanghai Tower, the particular deployment and implementation of each layer is discussed. A two tier database structure is applied to data management system to store data centralized. A B/S model data public system is established, providing web based data accessing and visualization. Utilizing the on line data port, a structure modal analysis system named structural monitor/analysis/evaluation software system(SMAE) is developed which can execute modal analysis and finite element dynamic characteristics analysis separately to provide a visualized comparison of the corresponding results. The result helps to the assessment of the dynamic behaviour of structure. Finally, the system effects are illustrated by examples. This prototype system is flexible on function integration and easy to expend and rebuild.
