［摘要］玻璃肋作為玻璃幕墻的支承系統(tǒng)可用在層高較高的大堂或共享空間區(qū)域，但由于生產(chǎn)和運輸不便等原因需要采用多塊肋板連接成一片整體。采用通用有限元軟件Strand7對玻璃肋的銷釘連接進行有限元分析，闡述了連接節(jié)點的受力與破壞機理，并將有限元數(shù)值分析結(jié)果與試驗破壞荷載值進行對比分析；最后，分析了接觸間隙大小和銷孔內(nèi)的彈性材料厚度對連接節(jié)點承載力設(shè)計值的影響，并給出了提高該類節(jié)點承載力設(shè)計值的建議。

Abstract:In the lobby with high floor height or shared space area, glass ribs can be used as the supporting system for the glass curtain wall. However, due to the inconvenience of production and transportation, it is necessary to connect a plurality of glass ribs into one piece. The finite element analysis of the pin connection of glass ribs was carried out by using the general finite element software Strand7. Finite element models were established for the joints tested. The loading mechanism and failure mechanism of the contact connection between the pin and the glass hole were illustrated and the finite element numerical results were compared with the test failure load. Finally, the influences of the contact gap size in the pin hole and the thickness of the elastic material on the capacity of the pin hole were considered, and the design recommendations were proposed to improve the bearing capacity of this type of joint.
Keywords:glass rib; pin connection; contact analysis; bearing capacity of joint
