N2 - Sensors with high accuracy, low cost, and easy integration into data acquisition system is one of the most important parts in structural health monitoring (SHM) system. In this paper, triaxial accelerometer and gyroscope embedded into the smartphones are utilized to monitor the vibration response of structure. However, in such an acquisition system, structural response data from different smartphones, compared to traditional wired accelerometers, is not always collected at the same time. So, nonsynchronous data processing technology is demonstrated comprehensively herein. First, the application based on Android operating system is described in detail. Modal identification method based on acceleration data which is collected asynchronously by different smartphones is introduced. Thus high performance SHM platform based on smartphones can be built. Then, numerical simulation study shows that modal identification method based on nonsynchronous data is feasible. At last, effectiveness and feasibility of SHM system based on the smartphones is proved in shaking table test on a three-story sheer frame building model.
