Abstract

The objective of this research is to develop and verify the wireless micro-electro-mechanical system (MEMS) monitoring system for the health monitoring of high rise buildings. The MEMS accelerometer has advantages of small size, low-cost and low power consumption, and thereby is suitable for wireless monitoring. Consequently, the use of MEMS and wireless communication can reduce system cost and simplify the installation for the structural health monitoring. To assess the applicability, the wireless MEMS monitoring system is applied to a full-scale building structure with hybrid mass damper (HMD) system. The building is a 5-story steel building and the HMD is mounted on the 4th floor to vibrate the building. The field evaluation results indicate that the wireless MEMS monitoring system is reliable and robust for the health monitoring of buildings.
