［摘要］近十余年來(lái)，我國(guó)高層建筑發(fā)展迅速，規(guī)模越來(lái)越大，高度越來(lái)越高。建筑高度的增加造成重力荷載越來(lái)越大，使結(jié)構(gòu)的豎向構(gòu)件，特別是柱子的截面越來(lái)越大。為了解決這一問(wèn)題，在設(shè)計(jì)高度較大的高層建筑時(shí)采用了鋼管混凝土柱。鋼管混凝土柱中的混凝土被鋼管包圍而受約束，處于三向受力狀態(tài)，與鋼管共同工作，具有很強(qiáng)的抗壓能力，因而柱截面可以大大縮小，效果顯著。隨著應(yīng)用的增多，應(yīng)用的方式亦趨于多樣化。以作者對(duì)鋼管混凝土柱的設(shè)計(jì)實(shí)踐及收集到的有關(guān)資料，對(duì)目前的使用情況作扼要的介紹，并展望今后的發(fā)展，供參考。

Abstract:In the recent ten years, the high rise buildings in our country developed rapidly. The buildings become huger and huger, taller and taller. As the height of the building increase, the load increases, and the vertical member, especially the column sizes, become bigger and bigger. To address this problem, concrete fill tube (CFT) steel columns are used in some higher buildings. Due to the core concrete is constrained by the steel pipe, it is in triaxial compress status. The strength-increased concrete and the steel pipe are working together and CFTs gain much high overall compress strengthens, therefore the column sizes can be designed substantial small. Also the application methods tend to versatile as the usages of the CFT increase. The application of the CFT in structural design, its relevant information we collected and its current usage status are introduced briefly. Its future development is prospected, which can be referenced by other colleagues.
Keywords:tall building; concrete fill steel tube; application; future perspective
