研究子结构刚度对巨子型有控结构位移响应的影响。结合刚度变化研究附加阻尼对巨子型有控结构的影响规律,并分析附加阻尼在巨子型有控结构中的作用。结合12种场地工况研究巨子型有控结构减震性能对地震激励的适应性。结果表明:附加阻尼可以改进子结构动力性能,确保巨子型有控结构在更宽的激励频率范围内工作,且将巨、子结构的侧移响应进一步降低;子结构刚度越小,附加阻尼对巨子型有控结构的影响越大;巨子型有控结构中,附加阻尼存在优化区间;子结构刚度对优化区间影响不大;装有附加阻尼的巨子型有控结构相比于未安装附加阻尼前,对子结构侧移控制率可达81.9%,对巨结构侧移控制率可达71.5%;巨结构侧移响应控制率对场地条件具有很好的适应性。
The effect of substructure stiffness on the displacement response of a giant-type controlled structure is investigated. The influence of the additional damping on the controlled structure of the mega-shaped structure is studied based on the change of the stiffness, and the effect of the additional damping on the controlled structure of the mega-shaped structure is analyzed. Combining with 12 kinds of site conditions, the adaptability of earthquake-induced excitation of meso-scale controlled structure was studied. The results show that additional damping can improve the dynamic performance of the substructure, ensure that the giant controlled structure works in a wider excitation frequency range, and further reduce the lateral response of the giant and substructures. The smaller the substructure stiffness, the additional damping The greater the influence of the giant-type controlled structure; the giant-type controlled structure, the additional damping there is optimization interval; substructure stiffness has little effect on the optimization interval; compared with the control structure without additional damping The control rate of the lateral displacement of the sub-structure was up to 81.9% and that of the giant structure was 71.5%. The control rate of the lateral response of the giant structure has a good adaptability to the site conditions.
