[提要] 介紹了重慶浪高凱悅大酒店工程有粘結(jié)預(yù)應(yīng)力扁梁的設(shè)計(jì)特點(diǎn)。設(shè)計(jì)中應(yīng)用有限元程序，分析了梁
柱剛度對梁軸向預(yù)壓力的影響。通過對柱及墻體預(yù)留后澆帶減小了豎向構(gòu)件對預(yù)應(yīng)力梁的約束作用，降低了梁中的次軸力，使設(shè)計(jì)經(jīng)濟(jì)合理。其設(shè)計(jì)思想可供同類工程設(shè)計(jì)參考。
[關(guān)鍵詞]有粘結(jié)預(yù)應(yīng)力混凝土 寬扁梁 剛度 有效預(yù)壓軸力The characteristic of design of bonded prestressed concrete flat beam of“lang-gao-kai-yue”International Hotel in Chongqing is introduced.The influence of the stiffness of beams and columns on available axial force of beam is discussed by finite element method. By adopting the post-poured belt devices and their construction joints of columns and walls, the lateral restraints and secondary axial force of beams are reduced.There are certain reference values for similar engineering design.
Keywords: bonded prestressed concrete; flat beam; stiffness; available axial force參 考 文 獻(xiàn)
