摘要
提出一种新型跨中截断式可更换耗能钢连梁的设计方案,利用有限元分析软件ABAQUS建立了新型跨中截断式可更换钢连梁的非线性有限元模型,并将设有新型钢连梁阻尼器的联肢剪力墙结构与传统钢筋混凝土连梁-剪力墙结构的变形云图、滞回曲线、骨架曲线以及层间位移作了对比分析。分析结果表明:设有新型阻尼器连梁的联肢剪力墙结构滞回曲线最外环所包含的面积大致为传统混凝土连梁-剪力墙结构的1.886倍,提高了结构的抗震性能,且具有较传统混凝土连梁-剪力墙结构更大的极限承载力和抗侧刚度,并具有震后灵活更换的优点。
A new design scheme of the bisected replaceable steel coupling beams is put forward,the nonlinear finite element model of the new bisected replaceable steel coupling beams and is established by finite element analysis software ABAQUS. And the comparative analysis of deformation figure,hysteresis curve,skeleton curve,displacement between the layers curve about shear wall structure of between steel damper coupling beam and traditional reinforced concrete coupling beam is carried out. The analysis results show that the area of hysteresis curve of shear wall structure equipped with steel coupling beams damper contains approximately 1. 886 times than that shear wall structure of conventional reinforced concrete coupling beams. The shear wall structure equipped with steel coupling beams damper improves the seismic performance and ultimate bearing capacity and limb lateral stiffness of structure,and has the advantages of flexible replacement after the earthquake.
