Abstract

Bond-slip relationship is very complex issue in the non-linear finite element analysis of beams. Three model beams with different bond length were constructed to study the mechanical properties. Based on the geometric parameters of the model beam as well as bond-slip curve obtained from experiments by former scholars, this paper has simulated the bond-slip relationship between steel bars and concrete with spring element COMBIN39, and conversion technology from bond-slip curve to spring element F-D curve is proposed. Based on the powerful ANSYS post-processing capacity, a detailed study considering the issue of bond-slip relationship is carried out. The result has enriched the numerical simulation theory of beams in a certain extent.
