| 摘 要： | 使用MTS液压伺服加载系统对一座1/3比例的钢框架模型进行了子结构拟动力试验.对试验子结构分别采用单自由度和多自由度,研究在子结构拟动力试验中试验子结构自由度数对整体结构响应的影响.试验结果表明当结构只有底层可能发生弹塑性变形时试验子结构的自由度数对整体结构响应的影响很小,在子结构拟动力试验中试验子结构采用单自由度和多自由度得到的试验结果趋于一致,均能较为准确地得到整体结构在给定地震波输入下的地震反应.

| Abstract: | The substructure pseudodynamic test was implemented on a two-story steel frame with 1/3 scale by using MTS computer-actuator on-line system.Substructure pseudodynamic tests that the tested substructures are single-degree of freedom(SDOF) system and multi-degree of freedom(MDOF) system respectively were carried out,and the influence of the number of freedom degree for the tested substructure on the whole structural responses was investigated. The investigated results indicate that the influence of the number of freedom degree for the tested substructure on the whole structural responses is small,and in substructure pseudodynamic tests,the results that are obtained by adopting the SDOF tested substructure are mostly coincident with the MDOF. |
