A.預(yù)應(yīng)力筋的張拉控制應(yīng)力必須符合設(shè)計(jì)規(guī)定
B.預(yù)應(yīng)力筋采用應(yīng)力控制方法張拉時(shí),應(yīng)以伸長(zhǎng)值進(jìn)行校核
C.伸長(zhǎng)值應(yīng)從初應(yīng)力時(shí)開(kāi)始量測(cè)
D.實(shí)際伸長(zhǎng)值與理論伸長(zhǎng)值的差值應(yīng)符合設(shè)計(jì)要求
E.設(shè)計(jì)無(wú)規(guī)定時(shí),實(shí)際伸長(zhǎng)值與理論伸長(zhǎng)值之差應(yīng)控制在8%以內(nèi)
