(五洲工程設(shè)計研究院，北京100053)[摘要] 以鋼管混凝土梁和鋼索組成的張弦結(jié)構(gòu)，充分利用了二者的受力特點，在工程中取得了良好的應(yīng)用效果。本文結(jié)合工程實例，簡要論述鋼管混凝土張弦結(jié)構(gòu)的設(shè)計過程，通過對比分析對設(shè)計和施工過程中的關(guān)鍵問題，如結(jié)構(gòu)選型、節(jié)點連接、混凝土澆筑等進行了較為深入地論述，最終得到了一些有益的結(jié)論。

( Wuzhou Engineering Design and Research Institute, Beijing 100053)Abstract: The CFST beam string structure, which is made up of CFST beam and steel cable is well used in the civil engineering. The excellent mechanical behavior comes from the full application of the constituent members. The design procedure was discussed in this paper by a living project. Based on the analysis results, the main issues in the design and construction were studied, such as structure style choice, joint design, concrete casting and so on. Finally some good proposal was achived.
Keywords: the beam string structure; concrete filled steel tube( CFST); joint, concrete casting
