Abstract

With the development of materials science and technology, extensive experimental research has been conducted on the properties of PVA steel hybrid fiber-reinforced cement-based composites. However, due to external and human factors, errors and relative limitations have occurred. Therefore, the use of numerical simulation methods can comprehensively reflect the seismic performance of components, providing sufficient basis and reliable theoretical basis for experiments and engineering applications. This article studies the seismic performance of PVA steel HyFRCC columns based on the OpenSEES platform, including the following aspects: using the bond slip model and fiber model considering the bond between steel bars and concrete as the constitutive relationship of PVA steel HyFRCC materials based on the OpenSEES platform, finite element analysis was conducted on PVA steel HyFRCC columns, and compared with experimental results. The results show that compared with the experimental results, the simulated hysteresis curve, skeleton curve, peak bearing capacity, displacement ductility coefficient, and equivalent viscous damping coefficient have smaller errors, indicating that the constitutive model is suitable for studying the seismic performance of PVA steel HyFRCC columns. Based on the OpenSEES platform, the influence of different axial compression ratios on the seismic capacity of PVA steel HyFRCC columns was studied using the above model. The results indicate that as the axial load ratio increases, the stiffness degradation becomes faster, and the energy dissipation performance and ductility gradually decrease.
