Hybrid Simulation Study on Cooperative Deformation of Nonlinear Steel-Cable Structure

摘要

In this paper, a hybrid simulation test method is used to study the cooperative deformation of nonlinear steel-cable structures. The general structural deformation analysis methods include the overall structure model test method and the numerical simulation method. The overall structure model test method is costly and the process is complicated; the numerical simulation method requires high requirements and requires prior knowledge of the constitutive relationship of the structure or component. The hybrid simulation test method combines the advantages of the two, that is, the entire structure is divided into two, one part is used as a test substructure for model testing, and the other is used as a numerical substructure for numerical simulation. In this study, the nonlinear cable is used as the experimental substructure for model test, and the rest of the cable is used as the numerical substructure for numerical simulation. Through the synchronous interactive feedback of the data between the two, the combined deformation of the nonlinear frame-type steel-cable structure is gradually obtained. Finally, the results of the hybrid simulation test are compared with the results of the numerical simulation test to verify the effectiveness of the hybrid simulation test method. The research in this paper can provide a new method for the combined deformation calculation of nonlinear steel-cable structures.
