摘　　要：隔震作为一种高效可靠的技术,已在工程结构中得到广泛应用,以提升其抗震性能。随着隔震支座尺寸的增大和新型支座(如高阻尼橡胶支座与摩擦摆支座)的开发,传统的试验方法在测试抗震性能方面面临新的挑战。例如,压剪试验或振动台试验无法准确再现隔震支座与结构之间的动态相互作用。而混合试验通过将隔震结构划分为数值子结构和实验子结构(隔震支座),为研究隔震结构的非线性和动态特性提供了一种有效手段。子结构技术使得混合试验能够以经济高效的方式进行大规模和全尺寸实验。本研究综述了混合试验方法在隔震结构中的应用,首次介绍了隔震结构的拟动态子结构试验、实时混合试验以及振动台混合试验。同时,详细讨论了混合试验方法面临的挑战,包括子结构建模、在线模型更新及力-位移混合控制策略的实施。Seismic isolation,as an efficient and reliable technolog.y,has been widely used in engineering structures to enhance their seismic performance.With the increase in the size of seismic isolation bearings and the development of new types of bearings such as high damping rubber bearings and friction pendulum bearings,traditional testing methods are facing new challenges in testing seismic performance.For example,compression shear tests or vibration table tests cannot accurately reproduce the dynamic interaction between seismic isolation bearings and structures.The hybrid experiment provides an effective means for studying the nonlinear and dynamic characteristics of seismic isolation structures by dividing them into numerical substructures and experimental substructures(seismic isolation bearings).Substructure technology enables mixed experiments to be conducted on a large scale and at full scale in an economically efficient manner.This study reviews the application of hybrid testing methods in seismic isolation structures,introducing for the first time the pseudo dynamic substructure test,real-time hybrid test,and vibration table hybrid test of seismic isolation structures.Meanwhile,the challenges faced by hybrid testing methods were discussed in detail,including substructure modeling,online model updates,and implementation of force displacement hybrid control strategies.
