A mega‐frame with a vibration control substructure (MFVCS) is a tuned mass damper system that converts substructures into a tuned mass. In this study, a kind of MFVCS using lead–rubber bearings (LRBs) to connect the vibration control substructure to the mega‐frame was proposed. To investigate the damping effect of this MFVCS, a series of shaking table tests were conducted, and the seismic responses of the MFVCS were compared with those of the traditional mega‐frame structure (TMFS). The results show that the seismic responses of the MFVCS are clearly smaller than those of the TMFS; additionally, the proposed MFVCS can provide a sufficient damping effect under different ground motions. Finite element (FE) models of the TMFS and MFVCS were established and validated by experimental results. Finally, the simulation results adopting different LRB models (equivalent linear and nonlinear elements) were compared, and the results indicate that simulation results can be obtained with greater accuracy from the FE model with a nonlinear LRB model than that with a linear LRB model.

带有振动控制子结构的大型框架的振动台模型测试

具有振动控制子结构（MFVCS）的巨型框架是调谐质量阻尼器系统，可将子结构转换为调谐质量。在这项研究中，提出了一种使用铅-橡胶轴承（LRB）将振动控制子结构连接到大型框架的MFVCS。为了研究这种MFVCS的阻尼效果，进行了一系列的振动台测试，并将MFVCS的地震响应与传统巨型框架结构（TMFS）的地震响应进行了比较。结果表明，MFVCS的地震响应明显小于TMFS。另外，提出的MFVCS在不同的地面运动下可以提供足够的阻尼效果。建立了TMFS和MFVCS的有限元（FE）模型，并通过实验结果进行了验证。最后，
