High‐strength steel framed‐tube structures with shear links (HSSFT‐SLs) exhibit better performance under seismic loading than conventional steel framed‐tube structures. In this study, the optimum lateral force distribution considering the higher mode effects in an inelastic state for the seismic design of HSSFT‐SLs was investigated to overcome the shortcomings of existing lateral force distribution patterns. A series of example structures with expected yield mechanisms were designed, and their finite element (FE) models were developed by using OpenSees program. The modeling approach was verified using experimental data. The influence of several important parameters on the lateral force distribution in the inelastic state was investigated. An optimum lateral force distribution in inelastic state was obtained by using the relative distribution of the maximum story shears of the FE models obtained from nonlinear time history analyses. The accuracy and effectiveness of the proposed lateral force distribution were assessed through comparison with code‐specified lateral load patterns. The suggested lateral force distribution exhibits more rational and higher precision than other patterns in the inelastic state and may provide a useful reference for further research regarding the design of HSSFT‐SL systems.

剪力连接高强度钢框架结构抗震设计的非弹性侧向力分布

具有抗剪连接（HSSFT-SLs）的高强度钢框架结构在地震荷载下表现出比传统钢框架结构更好的性能。在这项研究中，研究了考虑到在非弹性状态下较高模态效应的HSSFT-SLs抗震设计的最佳横向力分布，以克服现有横向力分布模式的缺点。设计了一系列具有预期屈服机制的示例结构，并使用OpenSees程序开发了它们的有限元（FE）模型。使用实验数据验证了建模方法。研究了几个重要参数对非弹性状态下侧向力分布的影响。通过使用从非线性时程分析获得的有限元模型的最大故事剪力的相对分布，可以得到非弹性状态下的最佳横向力分布。通过与规范指定的横向载荷模式进行比较，评估了所建议的横向力分布的准确性和有效性。在非弹性状态下，建议的侧向力分布比其他模式表现出更合理，更高的精度，并且可以为有关HSSFT-SL系统设计的进一步研究提供有用的参考。
