By adopting the optimized bp network to process damage detection on a rectangular beam , satisfactory outcome is gained 應(yīng)用該優(yōu)化的bp網(wǎng)絡(luò)對(duì)工程上最常見(jiàn)的矩形梁進(jìn)行了損傷識(shí)別,結(jié)果令人滿意。
In local model , the different kind of suspension girder ? i and rectangular beam make different field of velocity characteristic surrounding through two - dimensional velocity experiment . result display i has more influence to velocity around beam than rectangular beam 文章同時(shí)進(jìn)一步采用選進(jìn)的投影尋蹤法對(duì)試驗(yàn)數(shù)據(jù)作了優(yōu)化處理,使其結(jié)果更加可靠,更具實(shí)用價(jià)值,以供同類(lèi)型工程設(shè)計(jì)時(shí)參考
At the end of introduction , the paper presents the study content . nine rectangular beams were tested and the beams strengthened using prestressed carbon fiber sheet were compare with beams strengthened using non - prestressed carbon fiber sheet , in order to evaluate the effect of externally bonded prestressed carbon fiber reinforced plastic reinforcement on the cracking load , ultimate load and flexural stiffness of reinforced concrete beams 本文進(jìn)行了9根受彎試件的試驗(yàn)研究,對(duì)比了預(yù)應(yīng)力碳纖維布加固的受彎構(gòu)件與非預(yù)應(yīng)力碳纖維布加固的受彎構(gòu)件的開(kāi)裂荷載、極限荷載、抗彎剛度等工作性能,分析了預(yù)應(yīng)力對(duì)這些性能的影響。
