COMPARATIVE STUDY ON DESIGN CALCULATION ACCURACY OF STRUCTURE WITH ENERGY DISSIPATION DEVICES
-
摘要: 采用57条天然地震波，分别采用复模态设计方法、强解耦振型分解法、《建筑抗震设计规范》(GB50011-2001)基于变形能的等效阻尼法对消能减震设计方法的精度进行研究，得到了不同设计方法计算精度的初步规律，对消能减震结构设计具有参考价值。Abstract: The design calculation accuracy of structure with energy dissipation devices is studied using complex mode method with the data on 57 natural seismic waves, forcing decoupling method, equivalent damping method based on deformation energy according to Aseismic Design Code of Buildings(GB 50011-2001). The initial calculation accuracies among the different design methods is discovered. This is instructing significance for design of structure with energy dissipation devices.
