[摘要]某直徑33m單層球形網(wǎng)殼采用了無縫鋼管作為主要網(wǎng)殼桿件,并結(jié)合建筑美觀需求,其桿件匯交處的節(jié)點(diǎn)采用了新型板拼型焊接節(jié)點(diǎn)。重點(diǎn)介紹了該匯交節(jié)點(diǎn)在網(wǎng)殼彈性受力及幾何非線性受力模態(tài)下的節(jié)點(diǎn)有限元分析及其應(yīng)力分布特點(diǎn),也印證了其安全可靠的傳力機(jī)制,可為同類網(wǎng)殼節(jié)點(diǎn)形式的推廣應(yīng)用提供參考。

Abstract: The diameter of a single layer latticed shell is 33 meters, which adopts the seamless steel tube component. The joint of the single layer latticed shell is a new type. The safety of the node in the elastic force and geometric nonlinearity was introduced, which can provide reference for the the same kind of the shell joint.
Keywords: single layer latticed shell; latticed shell joint; new type joint; finite element analysis; geometric nonlinearity
