［摘要］在總結(jié)現(xiàn)有防屈曲支撐的截面形式、構(gòu)成特點(diǎn)以及設(shè)計(jì)理論的基礎(chǔ)上，提出了一種新型的防屈曲耗能支撐，即型鋼組合裝配式防屈曲支撐。介紹了這種新型防屈曲支撐的截面形式以及連接構(gòu)造，并對(duì)其基本性能和設(shè)計(jì)方法進(jìn)行了研究，提出了有效約束比的確定方法、外圍約束構(gòu)件螺栓強(qiáng)度驗(yàn)算方法和間距控制原則、內(nèi)核與外圍之間空隙的控制要求。

Behavior and application of buckling-restrained braces assembled with section steels

Guo Yanlin, Jiang Leixin(Department of Civil Engineering, Tsinghua University, Beijing 100084, China)

Abstract:A new type of buckling-restrained braces is put forward, named as the buckling-restrained braces assembled with section steels, in which the section steels are used to assemble the restraining subassembly. The different section types and joint types of buckling-restrained braces are outlined and corresponding design methods are obtained with the help of the primary theory derived and FEA results obtained, including the prediction of effective restraint ratio, the strength verification of bolts and controlling distance between bolts, as well as the controlling gap between core subassembly and restraining subassembly.

Keywords:buckling-restrained braces assembled with section steels; elastic buckling load; core subassembly; restraining subassembly; effective restraint ratio
