摘要
为研究耗能梁段长度对高强钢组合 D 型偏心支撑框架的受力性能的影响，采用 ABAQUS 有限元分析软件，建立了8种不同长度的耗能梁段高强钢组合 D 型偏心支撑钢框架（耗能梁段及支撑为 Q345钢，梁和柱为Q460钢）有限元模型，对其滞回性能进行非线性有限元分析。结果表明：高强钢组合 D 型偏心支撑钢框架结构形式具有良好的耗能能力；耗能梁段长度对结构的强度、刚度、延性及耗能性能均有较大影响。随着耗能梁段长度的增加，剪切屈服型结构的刚度及承载力均降低，延性和耗能能力增强。最后，根据有限元模拟结果得到耗能梁段长度取（0.96-1.38）Mp / Vp较为合理。
The length of links was studied to reveal its influence on seismic performance of type D eccentrically braced frames combined with high strength steel （D-HSS-EBFs）. Eight D-HSS-EBFs finite element models with different length of links were established by the finite element software ABAQUS, and non-linear hysteretic analysis were conducted. Results indicate that D-HSS-EBFs have good seismic performance while the links have good energy dissipation capacity, and the differ-ent length of links influences the strength, rigidity, ductility and energy dissipation capacity of struc-ture obviously. Load-carrying capacity and stiffness of structures decrease with the increase of link length, while the ductility and energy dispassion capacity become better. The suggestion on design of the reasonable range of the length of link is （0. 96 ~ 1. 38）Mp / Vp .
