摘要(Abstract):

对单个锚栓抗拉承载力进行了试验研究和有限元分析,两者结果基本吻合,验证了锚栓承载力试验的可靠性和有限元分析方法的合理性,由此得到的锚栓本构关系可为受拉柱脚节点研究提供参数,同时也为实际工程提供参考。数值分析考虑了锚栓和混凝土接触面粘结滑移非线性,采用面面接触来模拟锚栓与混凝土的共同工作,较能反映实际受力情况。
The tests data of tension bearing capacity for single anchor bolt are compared with the results of finite element analysis,which can verify the reliability of tests and reasonability of the finite analysis method.The constitution properties of anchor model acquired from tests or FEA can be used to offer parameters for analyzing the behavior of column base and propose design recommendations in practical engineering.By considering the nonlinearity of the interface slip,the mode of surface to surface contact is adopted to simulate the interaction of anchor and concrete as a whole.Such numerical model can reflect the actual load situations satisfactorily.
