[提要] 介紹杭州市某無粘結(jié)預(yù)應(yīng)力混凝土結(jié)構(gòu)應(yīng)力一應(yīng)變現(xiàn)場實(shí)測試驗(yàn)，對張拉階段監(jiān)測結(jié)果和靜荷載試驗(yàn)結(jié)果進(jìn)行了分析，得出了對工程設(shè)計(jì)有意義的結(jié)論。
[關(guān)鍵詞] 無粘結(jié)預(yù)應(yīng)力混凝土 現(xiàn)場實(shí)測 應(yīng)力應(yīng)變Field measurements on an unbonded prestressing concrete structure are described. The main results of load test and strand post-tension process measurement are proposed. Some conclusions based on test are helpful to design unbonded prestressing concrete structures.
Keywords: unbonded prestressing concrete; field measurements; post-tension process
