摘要
在工程设计中,柱脚节点一般被视为"刚接"或"铰接"以简化设计过程,但事实上,柱脚节点往往介于两者之间,属于"半刚性"节点。刚性柱脚节点实际上具有有限的转动能力。本文针对外露式刚性柱脚节点,利用现有试验结果进行有限元模拟和校对,给出了可靠、适用的ABAQUS有限元建模和分析方法,并对四锚栓外露式刚性柱脚节点进行了有限元参数分析,得出影响柱脚节点受力性能的主要因素:底板厚度、锚栓直径、锚栓位置、轴压比。
The design of joints was performed as considering that theyare“ rigid’, or“ pinned’,.But, inmostcases, thejointsex- hibit an intermediate behavior, termed semi - rigid. This paper aimed to take advantage of the existing test results to build relia-ble FE model,and then use this FE model to perform parametric analysis. The results showed that the key factors which affectthe mechanical property of the exposed rigid column base are as fol-lows :the thickness of the plate, the diameter of the bolt, the po-sition of the bolt and the ratio of axial compression stress to strength.
