摘　　要：预制管混凝土复合结构分为外层高性能预制管和核心区混凝土。高性能预制管在工厂进行生产,然后在工地现场进行起吊,将核心区混凝土注入其中,这种建筑形式融合了预制和混凝土现浇的方式,具有创新性。研究表明,预制管混凝土节点在抗震性能方面表现良好。利用ABAQUS软件进行建模以及运算,我们建立了相同体积、强度和配筋率的试样品有限元模型,运用静态加载的方式去施加荷载,并研究了试样品是如何破坏的。对预制管混凝土和普通混凝土有限元模型的抗震性能进行了对比分析,结果显示预制管混凝土模型具有更佳的抗震性能。The precast concrete composite structure consists of high-performance precast pipes as the outer layer and core concrete in the central area.These high-performance precast pipes are manufactured in factories and then lifted into place at the construction site,where the core concrete is poured into them.This construction method combines the advantages of pre-casting and cast-in-place concrete,showcasing innovation.Studies have shown that precast concrete nodes exhibit excellent seismic performance.Using the ABAQUS software for modeling and computation,we established finite element models of test specimens with identical volumes,strength,and reinforcement ratios.Static loading was applied to the specimens to study their failure modes.Comparative analysis of the seismic performance between precast concrete and conventional concrete finite element models revealed superior seismic performance in the precast concrete model.
