随着建筑技术的不断发展,诞生了越来越多的大跨度结构及高耸结构等钢结构工程,而这些结构一般固有频率很低、内部阻尼很小,在受到人群同步激振或风荷载激振时,往往会激发共振而影响结构的正常使用。采用调谐质量减振器TMD可有效地增加结构的系统阻尼,控制结构的振动。通过上海浦东机场登机桥、广州亚运会历史馆和杭州湾观光塔等工程实例,介绍调谐质量减振器TMD的原理及其在钢结构中的应用。
With the continuous development of building technology, more and more steel structure projects such as long-span structures and towering structures have been born. These structures generally have low natural frequencies and small internal damping. They are subject to synchronous or wind- When the vibration, often will stimulate the resonance and affect the normal use of the structure. Using tuned mass damper TMD can effectively increase the structural damping of the structure and control the vibration of the structure. Through the engineering examples of boarding bridges at Shanghai Pudong Airport, the Guangzhou Asian Games History Museum and the Hangzhou Bay Observation Tower, the principle of the tuned mass damper TMD and its application in steel structures are introduced.
