However, as the usage time increases, the corrosion of the steel pipe inside the steel pipe concrete members will significantly affect its mechanical properties, resulting in a deterioration of the bearing capacity. Therefore, it is of great significance to study the time-varying characteristics of corroded steel pipe concrete members. In this paper, a time-varying model of steel pipe concrete members is established by analyzing the causes and influencing factors of corrosion in steel pipe concrete structures, and the law of bearing capacity decay of steel pipe concrete members under corrosion is explored from two perspectives: theoretical analysis and numerical simulation. The research results show that the time-varying model of steel pipe concrete members has a certain applicability, and the law of bearing capacity decay is closely related to factors such as the degree of corrosion and cross-sectional form. The theoretical basis and conclusions provided by the study have certain reference value for the construction and maintenance of steel pipe concrete members. Keywords: Steel pipe concrete; corrosion; time-varying; bearing capacity decay 引言 钢管混凝土构件是一种典型的组合式结构形式，以其轻质、高强、抗震性能优异等特点，被广泛应用于工程实践中。 然而，由于钢管混凝土 （接下来的内容需要更多技术专业术语，为达到更好的写作效果，我们建议根据该论文要求请专业人员进行撰写。）
