本文对考虑土-结构相互作用的超高层钢框架进行了大规模地震反应分析。生成了一个由31层超高层钢框架及其下面的地面组成的高保真网格，该网格完全由六面体单元组成。将与一维(1D)波传播分析解一致的边界条件施加于地面的侧面和底面。假定波在垂直方向上传播。一维波的传播分析是在1995年Hyogoken-Nanbu地震的JR Takatori记录的激励下进行的。并行大规模分析是使用世界上速度最快的超级计算机之一的K计算机进行的。对有地基和无地基两种模型的计算结果进行了比较，结果表明，由于本研究假设地基足够坚硬，两种模型得到的结果非常相似。
In the present study, a large-scale seismic response analysis of a super-high-rise steel frame considering the soil–structure interaction is conducted. A high-fidelity mesh of a 31-story super-high-rise steel frame and the ground underneath it, which is made completely of hexahedral elements, is generated. The boundary conditions that are consistent with the solution of the one-dimensional (1D) wave propagation analysis are imposed on the side and bottom surfaces of the ground. The waves are assumed to propagate in the vertical direction. The 1D wave propagation analysis is conducted under the excitation of the JR Takatori record of the 1995 Hyogoken-Nanbu earthquake. The parallel large-scale analysis is performed using the K computer, which is one of the fastest supercomputers in the world. The results of the models with and without the ground are compared, which reveals that the results obtained by these two models are very similar because the ground is assumed be sufficiently hard in the present study.
