The research subject is to develop a finite element modeling method to reproduce the bending stiffness of IWRC 6×Fi(29) wire ropes for cranes. Since IWRC 6×Fi(29) is made of steel wire instead of fiber in the center of the rope, there are many contact points between wires. Therefore, a high level of reproducibility of contact conditions between wires is required. In this study, Fi(29) strands, IWRC and IWRC 6×Fi(29), which consists of these strands, are the object of analysis. A rope model eliminated initial penetrations between wires by the dynamic relaxation analysis and modeling of a three-point bending test was conducted. For validation, the experimental and analytical results were compared, and the slope and hysteresis of the load-displacement curves were well represented in the analysis. Furthermore, it was confirmed that the analytical values of the rope flexibility obtained by the load-displacement curve approximately matched the experimental values and that the bending deformations of the rope can be expressed in the analysis.
