摘要

The performance of helical-effect of the helical and twisted material is elaborated in this paper. Through analyzing the parameter of the helical and twisted material, a mechanism model based on the bond of anchorage is built. Furthermore the fundamental derivation formula is done and the sensitivity is analyzed. Based on systematic study of bond anchorage performance of helical and twisted reinforcement material, the mechanical of the helical-effect was theoretically analyzed and quantitatively studied. The relationship between pullout and bond slip was studied by mechanical analysis and mathematical modeling stage by stage, the formula was established and derived. As a result, theoretical understanding of the helical-effect was deepened, providing the theoretical basis for optimization of material properties, geometry parameters and developing new materials.
