Abstract

Abstract

In order to study the effects of size effect on the existing axial compressive performance of reinforced concrete columns strengthened with prestressed steel strips, a finite element analysis model was established based on the axial compressive test of steel strip reinforcement columns. The finite element analysis results were verified by experimental results. On this basis, the effects of different cross-section dimensions on the axial compression perfomance of steel strip reinforcement members were studied when the components were similar. The results showed that the increase in compressive strength and the increase in axial stiffness of similar members decreased with the increase of the cross-sectional dimensions of the members. The size effect coefficient was used to establish the calculation formula of the axial bearing capacity of the steel strip reinforcement column considering the size effect. The calculated values agreed well with the simulated values.
- prestressed steel strip,
- finite element,
