[提要] 在網(wǎng)殼中施加預(yù)應(yīng)力,可有效地調(diào)節(jié)各桿件及球節(jié)點(diǎn)內(nèi)力,減小結(jié)構(gòu)變形,同時(shí)可平衡網(wǎng)殼在支座處產(chǎn)生的水平推力。結(jié)合一工程實(shí)踐,介紹了預(yù)應(yīng)力筋在網(wǎng)殼中的布置形式及相關(guān)的預(yù)應(yīng)力設(shè)計(jì)施工技術(shù)。
[關(guān)鍵詞] 網(wǎng)殼 球節(jié)點(diǎn) 預(yù)應(yīng)力 支座The prestressing in the reticulated shell can effectively regulate the internal stress of the rod and node, decrease deformation, and balance horizontal thrust generating in the pedestal of the reticulated shell. Based on a project, the design and construction of prestressed reticulated shell structure and the arrangement of the prestressed bar are disserted.
Keywords: reticulated shell; global node; prestressed; pedestal
