Abstract

Abstract

The three-dimensional nonlinear finite element analysis of the bending properties of prestressed steel-bamboo composite I-beams was carried out by using the finite element software ABAQUS, the anisotropy and yield criterion of recombinant bamboo were considered in the model, the cohesion element was introduced to simulate the bonding slip of the steel-bamboo interface, and the simulation results were compared with the test results, and the influence of prestress on the bending properties of the composite beam was discussed. The results showed that the failure characteristics, the load-deflection curves, the allowable load and the maximum mid-span deflection of the prestressed steel-bamboo composite beams in the test and simulation were consistent. The configuration of prestressed ribs could improve the stiffness of the composite beam, but with the increase of the prestress value, the stiffness of the composite beam did not change significantly, the ultimate bearing capacity and deformability were improved, and the failure of the glue layer at the steel-bamboo interface was delayed. When the prestress was too large, it would lead to premature degumming of the steel-bamboo interface of the composite beam and the reduction in the ultimate bearing capacity. In order to meet the requirements of bearing capacity and deformation performance, it was recommended that the prestress application value should be the allowable bearing capacity value of ordinary steel-bamboo composite I-beams.
