摘要:
工程中常常忽略销轴支座的平面外受力情况,可能造成在偶然的、较大的平面外水平荷载作用下耳板的折断.新型销轴支座中橡胶垫的加入改善了传统销轴支座承受平面外水平荷载作用下受力与变形的不确定性.文章利用ABAQUS软件建立新型支座的有限元模型,模拟其在平面外水平荷载作用下的力学性能,通过与现有的试验结果对比,验证了有限元分析的合理性.并进一步运用有限元的结果分析得到了支座的屈服机制、荷载传递规律和影响极限承载力的主要因素.
Abstract:
The behavior of pinned connection under horizontal force in the out-of-plane direction is often neglected in engineering, causing failure of the lugs under this kind of load. Adding the laminated rubber pad in the new pinned connection improves the uncertainty under the out-of-plane force. Finite element models established by ABAQUS were used to research the horizontal performance of the connection. Results obtained from finite element analysis were compared with those from experiment. The comparison indicated the reasonableness of finite element analysis. The yield mechanism, transformation of the load and important factors that affected the horizontal ultimate bearing capacity of the connection in the out-of-plane direction were revealed through finite element analysis.
