Partially prestressed technique is used in the ring beam to control the crack width and resist the circumferential tension forces. For the case of large hole on the cylinder structure, stress analysis was carried out and corners of the hole were strengthened.Keywords: concrete cylinder; prestressed ring beam; finite element analysis作者簡(jiǎn)介：陳磊，碩士，高級(jí)工程師，一級(jí)注冊(cè)結(jié)構(gòu)工程師，Email:lei.chen@siad-c.com。參考文獻(xiàn)［1］孟美莉，傅學(xué)怡，吳兵.卡塔爾某超高層建筑部分預(yù)應(yīng)力環(huán)梁設(shè)計(jì)研究［J］.建筑結(jié)構(gòu),2008,38(12):69-72.
