［摘要］通過對CFRP索懸掛結(jié)構(gòu)的現(xiàn)場試驗，對比分析了核心柱與懸掛樓面不同連接方式、不同形式荷載作用下，懸掛結(jié)構(gòu)中核心柱的應(yīng)力、CFRP索的軸力以及結(jié)構(gòu)關(guān)鍵部位的側(cè)移。試驗結(jié)果表明：布設(shè)橡膠墊可明顯減小懸掛樓面與核心柱之間的相對位移； 各形式荷載作用對核心柱上各位置處側(cè)移影響不大，但對各懸掛樓層與核心柱之間的相對位移影響較大，尤其是未布設(shè)橡膠墊時； 各形式荷載作用下，1號柱因離荷載作用位置最近，受力最為復(fù)雜，但CFRP索的軸力變化不大。

Abstract: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.
Keywords:CFRP cable; suspended structure; relative displacement; lateral displacement; rubber pad
