钢梁和箱型柱间翼缘板连接件的抗震性能

对钢梁和焊接箱型柱间的翼缘板连接件的滞回性能进行分析和试验研究。对3个足尺试件模型进行试验,从而评估翼缘板长度和板-翼缘角几何焊接对翼缘板连接件地震响应的影响。试验所用的翼缘板连接件符合AISC中对于特殊抗弯框架的抗震要求。因此,使用试验结果验证ABAQUS软件建立的有限元模型,此模型可用于对试件模型性能的进一步探讨。

Seismic Performance of Flange Plate Connections Between Steel Beams and Box Columns

This paper presents analytical and experimental studies on the cyclic behavior of flange plate connection between a steel beam and a welded box column.Three full-scale specimens were tested to evaluate the effect of flange plate length and plate-to-flange fillet weld geometry on the seismic response of flange plate connection.Flange plate connection in the test specimens achieved the AISC seismic provision requirements for special moment frames.Then ,the finite-element model developed using ABAQUS was validated using the test results.This model was subsequently used to further investigate the behavior of the test specimens.
