This article discusses the analysis of the joint punching shear of grouted offshore jacket leg and pile with the effective thickness of grouted element and presents three different methods to calculate the effective thickness of it with SACS program.

借助SACS程序提供了三種導管架灌漿腿柱的有效壁厚計算方法,舉例對采用有效壁厚及僅采用導管架的管壁厚對管節點進行沖剪應力計算對比,結果表明采用有效壁厚計算沖剪應力對優化導管架的設計,降低工程造價是完全可能的。

Measured and analysed were the punching shear stress, the value of vibration and the frequency spectrum under the working conditon of punch machine, and the shear, stress of the materials used to forge coins.

對沖壓機工作狀態下的沖剪力，振動量值和振動頻譜及造幣用材料的剪切應力進行了測試與分析。
