| 摘 要： | 通过对一个现有建筑的结构动态参数的辨识讨论了土与结构的相互作用.目标建筑是建于1998年的8层的型钢混凝土结构.在此研究中,8自由度的模型被建立以分析微震观测数据,随即,非参数和参数技巧以辨识此结构的自然频率,阻尼率和层硬度等.在考虑土-结构相互作用和不考虑土-结构相互作用的两种情况下,分别辨识结构的参数并对比结果以证... |

| Abstract: | The authors attempt to consider the effect of soil-structure interaction by identifying the dynamic parameters of an existing building.Target building is an 8-story steel encased reinforced concrete building,which was constructed in 1998.In the study,an eight-degree-of-freedom analytical model is utilized to analyze the data from microtremor measurement.Then,nonparametric and parametric techniques are employed to determine natural frequency,damping ratio and story stiffness of the structure.For these two ca... |
