摘要

摘要: 随着城市化进程的加速，以公共交通为导向的开发模式（TOD）在大型城市的广泛应用推动了轨道交通上盖建筑的发展。全框支厚板转换层结构凭借其较高的整体刚度以及灵活布置上部建筑的优点，成为满足TOD模式多功能布局需求下的重要方案。为探究相关参数对全框支厚板转换层结构抗震性能的影响，开展了参数化数值模型研究，揭示了斜交角度和厚板厚度对整体结构抗震性能的影响。结果表明：斜交角度的改变对该结构体系的动力特性影响有限，不同斜交角度的参数化模型第一振型周期最大差异仅为0.35%；在工程设计中，调整转换层厚板厚度可优化构件的应力分布并提高抗震性能，但厚板横截面尺寸的增大会对下部框支柱产生不利影响，在设计中应保证转换层厚板性能指标的同时慎重选择板厚，避免厚度过大对框支柱带来的抗震负担，即应综合考虑其对上下部结构的影响。

Abstract: With the rapid advancement of urbanization， the extensive application of the TOD model in large cities has driven the development of rail transit superstructure buildings. The full frame-supported thick-plate transfer layer structure， characterized by high overall stiffness and flexible upper-structure layout， has become a key solution for meeting the multifunctional requirements of TOD developments. To investigate the impact of key parameters on its seismic performance， a parametric numerical study was conducted， focusing on the effects of the oblique angle and thick plate thickness. The results indicated that variations in oblique angles had a limited influence on the dynamic characteristics of the structure， with a maximum difference of only 0.35% in the first-mode period among different parametric models. In engineering design， adjusting the transfer layer’s thick plate thickness could optimize stress distribution and enhance seismic performance. However， increasing the cross-sectional dimensions of the thick plate might exert adverse effects on the lower frame columns. Therefore， while ensuring the performance requirements of the transfer layer， careful selection of plate thickness is essential to prevent excessive seismic demands on frame columns， considering the integrated impact of both the upper and lower structures.
