摘要
本文对具有阻尼控制系统的高层建筑的模态特性进行了深入的理论分析和试验研究。文中对于具有非经典阻尼分布的建筑结构体系的模态分析，应用并发展了Ｖｅｓｅｌｉｃ的整体Ｊａｃｏｂｉ法，具有显著的优越性。研究表明，对高层建筑施加阻尼控制、随着阻尼控制系统的阻尼参数及其在建筑上的安装位置的变化，将显著地改变建筑的模态特性。最后通过对一三层框架建筑模型进行试验研究，从而验证了所取得的研究成果。
Theoretical analysis and experimental research for modal properties of multistory buildings with damper control systems are thoroughly performed in this paper. The Veselic's global Jacobi method is employed and advanced for the modal analysis of the systems of building structures with nonclassical damping distributions, which is shown to have significant advantages. The research shows that when damper control is introduced to the multistory buildings,the modal properties will be strikingly changed along with the variations of damping factors of the damper control systems and their positions on the buildings. Finally, a 3-story frame building model is tested to verify the research results.
