［摘要］浦東國(guó)際機(jī)場(chǎng)T2航站樓結(jié)構(gòu)Y形柱-梁連接鑄鋼節(jié)點(diǎn)中采用了以向心關(guān)節(jié)軸承作為轉(zhuǎn)動(dòng)核心的球鉸節(jié)點(diǎn)形式，實(shí)現(xiàn)了空間理想鉸接的結(jié)構(gòu)要求。該節(jié)點(diǎn)由向心關(guān)節(jié)軸承、銷軸、鑄鋼件等部分組成，構(gòu)造復(fù)雜，無(wú)法用常規(guī)方法確定其承載力。對(duì)該鑄鋼球鉸節(jié)點(diǎn)進(jìn)行了足尺試驗(yàn)，著重考察了向心關(guān)節(jié)軸承的傳力性能和轉(zhuǎn)動(dòng)性能；在試驗(yàn)基礎(chǔ)上進(jìn)行了有限元分析，得出了向心關(guān)節(jié)軸承節(jié)點(diǎn)的破壞機(jī)理，并提出了節(jié)點(diǎn)構(gòu)造改進(jìn)措施。

Abstract:A new type of articulated cast steel joint with radial spherical plain bearing (RSPB) was adopted to connect the Y-column and beam in Shanghai Pudong International Airport Terminal 2 to obtain three dimensional rotation and load transfer. This joint is composed of a RSPB, a pin shaft and steel castings, which is too complicated to be analyzed by traditional methods. The full-scale joint was tested to investigate the rotation and load capacity. Based on both FEA and experimental results, the failure mechanism of the RSPB joint is obtained and the joint details are improved.

Keywords:radial spherical plain bearing; articulated joint; joint experiment
