摘要
为了研究连柱钢框架结构的抗震性能,采用ABAQUS有限元分析软件建立了结构的有限元模型并对其进行循环加载分析,主要分析了耗能梁段长度、钢框架跨度和层高对结构滞回性能的影响。分析结果表明:连柱钢框架结构具有良好的滞回性能,可以较好地满足地震作用下的耗能要求;框架结构梁柱节点受力较大,可采用加厚腹板等方式加强;随着耗能梁段长度的增加,连柱钢框架结构的滞回性能不断提高,但增加到一定程度后,耗能梁段的塑性发展不充分;钢框架跨度对结构滞回性能的影响较小,层高的影响较为显著。
Several finite element models were established to investigate the hysteretic behavior of linked column frame,and the influence of link beam length,frame height and frame span were mainly considered. The results showed that the linked column frame had good hysteretic behavior and could well meet the energy dissipation requirement under the action of earthquake. The frame bore more force and need to be reinforced by increasing thickness of web. With the increase of the length of the link,the hysteretic behavior of the frame was improved,however,when the behavior increased to a certain extent,the plastic development of the link was unable to be completed. The frame height had a great influence on hysteretic behavior but the effect of frame span was very small.
