摘要:
为研究高强钢组合偏心支撑框架的抗震性能,采用ABAQUS有限元软件对5种不同耗能梁腹板厚度的高强组合钢偏心支撑钢框架(耗能梁段为Q345钢,梁柱及支撑为Q460钢)进行了有限元模拟分析.研究表明:在适当的范围内耗能梁段腹板厚度增大可提高结构的承载力、刚度及耗能能力,但过厚会因框架梁柱节点等处的破坏导致及耗能能力的降低,并根据有限元分析结果对耗能梁段的厚度给出了相关建议.
Abstract:
Five dual high-strength steel eccentrically braced frames(link for Q345steel,beam,column and brace for Q460steel)with different link thickness were analyzed with the method of finite element analysis(FEA)by ABAQUS. The results showed that the bearing capacity, stiffness and energy dissipation capacity of the structure increased gradually as the link web thickness increased in the appropriate range. However, the over thickness of the link web may lead to the link flexure yield and energy-dissipating capacity decline for the shear capacity of web is greater than the bending bearing capacity of flange. Finally, the related suggestions were given according to the results of the finite element analysis of the link thickness.
