建筑结构中阻尼器消能减震设计关键技术的探讨
|
摘要
阻尼器能有效地实现结构的消能减震,在中国也逐渐得到应用。为更好地促进阻尼器在我国的应用,解决当前对阻尼器应用的一些认识不足问题,结合主要由现代设计集团完成的带阻尼器消能减震结构工程应用情况,介绍了位移型和速度型阻尼器及其应用情况。结合国内工程界对阻尼器的研究和工程应用情况,探讨了一些阻尼器应用的关键设计技术问题,尤其是关于国内外抗震规范系统性的差异引起的阻尼器应用设计问题、采用阻尼器结构的计算分析技术、阻尼器的侧向稳定问题等,提出解决方法和今后研究的方向,供广大工程人员讨论。
Dampers can dissipate seismic energy and reduce the seismic effects on the structures effectively,and it has been applied in some projects in China.In order to prompt the application of dampers in China and solve the problems of lacking enough understanding on the applications of dampers,based on several projects,which are mainly designed by Shanghai Xiandai Architectural Design Group and adopted dampers to reduce the seismic effects,it is introduced that velocity-dependent and displacement-dependent dampers and their applications.Based on recent researches and applications in China,some key design problems are studied,some solutions or the endeavor goals in the future are put forward,especially the problems on the application of dampers from the difference between the aseismic codes of domestic and aboard,the analytical techniques upon the structures with dampers,and lateral stability of dampers,etc..These solutions or goals would benefit engineers.
