| Abstract: | To develop an integrated vibration monitoring and modal recognition software for building structures, the main work contents of monitoring and recognition calculation are analyzed ; the framework system and the professional functions are designed for the integrated software, and four primary function modules are schematized, including Internet-based remote monitoring client terminal, structural calculation, modal recognition and result comparison/evaluation. According to recognition theories, peak method in frequency domain and stochastic subspace method in time domain, a numerical algorithm for modal recognition based on in-situ vibration acceleration is designed. The software package is developed with C ＋ ＋ and FORTRAN program languages on Microsoft Windows platform, and it is verified with numerical testing examples. The software has been applied to the vibration monitoring and modal recognition in ＂Shanghai Tower＂ construction process. |
