Abstract:
The bonding section length affects the axial force and displacement of the anchor body. The paper uses a numerical method to build the model with the mesh size (length×width×height=6mx0.6mx4m), install a bolt in the middle of the model with the size of the plates is 150×150mm. The paper studied the effect bonding section length for the axial force and displacement of anchor body. These results show that the influence for 0,8m and 2,4 of the bonding section length for the axial force and displacement of anchor body in the anchor body. The research results help designing, constructing companies to have the basis for selection dimensions of anchor bonding section length.
