摘　　要：通过对CFRP索悬挂结构的现场试验,对比分析了核心柱与悬挂楼面不同连接方式、不同形式荷载作用下,悬挂结构中核心柱的应力、CFRP索的轴力以及结构关键部位的侧移。试验结果表明:布设橡胶垫可明显减小悬挂楼面与核心柱之间的相对位移;各形式荷载作用对核心柱上各位置处侧移影响不大,但对各悬挂楼层与核心柱之间的相对位移影响较大,尤其是未布设橡胶垫时;各形式荷载作用下,1号柱因离荷载作用位置最近,受力最为复杂,但CFRP索的轴力变化不大。Based on the field experiment of suspended structure with CFRP cables, the stresses of core columns, axial forces of CFRP cables and lateral displacements of key parts of the structure of core columns and suspended floors were compared under different connection modes and loads. The experimental results show that: the arrangement of rubber pad can significantly reduce the relative displacement between the suspended floors and the core columns;various forms of loads have little effect on the lateral displacement of each position on the core column, but have a greater impact on the relative displacement between the suspended floors and the core columns, especially when the rubber pad is not arranged. Under the action of various forms of loads, the stress of the No. 1 column is the most complex because it is the closest to the load position, but the axial force of CFRP cables has little change.
