摘要
根据模糊理论及抗震结构混合控制理论,利用MATLAB语言编制了一套能对被动调谐质量阻尼器(PTMD)及消能减震相结合的体系进行弹塑性时程分析的计算机程序。使用该程序对模型结构进行基于模糊的弹塑性时程分析,并与试验结果相对比,分析表明二者吻合较好。最后提出了PTMD及消能减震相结合的体系的实用设计方法,同时给出数值算例以证实该控制体系在降低结构地震反应方面的有效性。对推动结构控制理论的发展具有理论意义和实用价值。
In this paper, based on the fuzzy theory and hybrid control theory of aseismatic structure, a Matlab program is developed to conduct elastoplastic time history analysis of the energy dissipation system in combination with the passive tuned mass damper (PTMD). It is indicated that the analysis result fits very well with the test result. In addition, a practical design method combining the energy dissipation system with the PTMD is put forward, and a numerical example is given to demonstrate the effectiveness of the control system in reducing the structural earthquake response. It is expected that the present work is of both theoretical and application values in promoting the development of structural control theory.
