（同濟(jì)大學(xué) 上海 200092）[提要] 肩梁的剛度對于能否保證多肢柱上下柱之間的剛性連接有很大的影響。作者歸納了常見的多肢柱受力情況，提出了簡化計算圖式，用來分析為滿足上下柱之間剛性連接而對肩梁轉(zhuǎn)動剛度的要求。并提出了計算肩梁轉(zhuǎn)動剛度的方法。
[關(guān)鍵詞] 多肢柱 肩梁 剛度The stiffness of shoulderbeams is important to maintain the integrity of columns. The requirements for
the stiffness of shoulderbeams to keep the stiff connection between the upper and the lower parts of
columns are studied, by simplifying the shoulderbeam as a spring hinge. And a method to compute the stiffness of shoulderbeams is put forward.
Keywords: shoulderbeam; stiffness; polystyle column
