摘　　要：为了研究预埋FRP拉挤型材-混凝土复合柱受力性能,对其进行数值模拟。通过选取适当单元类型、材料属性以及划分网格,比较FRP-混凝土复合柱、传统钢筋混凝土和型钢-钢筋混凝土嵌入柱之间的结构性能。结果表明:FRP型材复合柱的抗压性能与钢筋混凝土柱接近,复合构件有效地补偿了结构受力不均,结构受弯性能和耐火性能有显著提升,显示出FRP-混凝土复合柱在工程应用中的可能性。To study the stress performance of concrete composite columns embedded with pultruded FRP profiles,numerical simulations were conducted.By selecting appropriate element types,material properties,and mesh divisions,the structural performance of FRP-concrete composite columns was compared with traditional reinforced concrete columns and steel-reinforced concrete embedded columns.The results indicate that the compressive performance of FRP composite columns is comparable to that of reinforced concrete columns.The composite components effectively compensate for uneven stress distribution in the structure,resulting in significant improvements in bending performance and fire resistance.This suggests the potential application of FRP-concrete composite columns in engineering.
