| 中文摘要 | 实时耦联动力试验是一种新型的结构动力试验方法,该试验方法将子结构概念引入到实时加载的试验系统中, 既能克服常规振动台试验对于试验规模的限制,又能克服拟动力子结构试验中无法考虑加载速率影响的问题.本文首先介绍了实时耦联动力试验方法的基本思路,并阐述了构建试验系统的基本技术要求,随后对实时耦联动力试验中的数值计算方法、作动器迟滞补偿、多点输入试验等关键问题的研究现状做了评述。最后,简单介绍了清华大学正在实施建设的双振动台实时耦联动力试验系统及其应用前景。; Real-time dynamic hybrid testing (RTDHT) is a novel structure testing method developed in recent years.Because of the application of sub-structuring technique,RTDHT avoided the specimen scale limitation, which is inevitable in traditional shaking-table tests.Meanwhile,the rate dependent behavior of testing materials could be considered because the tests are operated in real-time.In this paper,the basic idea and technique requirements in system setup of RTDHT is introduced and reviewed.The state of the art and research advances mainly in three directions are described,i.e.real-time numerical calculation,actuator delay compensation and multi-actuator testing method.In addition,the Dual-shaking-table RTDHT testing system which is being constructed at Tsinghua University is also introduced.The potential applications of such testing system in earthquake engineering in the future are discussed. |
