设计出一种新型埋件,该埋件用一定数量的型钢替代部分锚筋进而提高埋件抗剪承载力.完成材料性能试验后,制作了3种规格的工字钢剪切键埋件作为试验组、3种规格纯锚筋埋件作为对照组,进行对比加载试验.在试验研究的基础上,采用通用有限元分析软件ABAQUS建立了数值模型,对埋件受剪作用进行模拟.将有限元分析结果与试验结果进行对比,两者吻合较好.研究结果表明:锚筋的抗剪刚度较低,工字钢剪切键能有效提高埋件的抗剪刚度;工字钢剪切键埋件破坏始于埋件的相对滑移,表现为塑性破坏,满足安全性要求;在埋件抗剪体系中,工字钢剪切键与锚筋能很好地协同工作.“,”In order to improve the shearing behavior of embedded part,a new kind of embedded part where H-steel shear key replaced anchor bar is designed.After material property test,three different specifica tions of H-steel shear key and anchor bar are loaded for contrast.A finite element(FE) model is built up by using general FE analysis software ABAQUS based on experimental study.The FE analysis results show good agreement with the experimental results.The research showed that H-steel shear key could help increase the shear stiffness and it is superior to the anchor bar;embedded part destruction began with the slip failure of the embedded parts,which behaved mostly as the characteristics of plastic failure and meeting the requirements for safety;the efficiently combination of H-steel shear key and anchor bar provided an effective shear resistance system for embedded part.
