例句與用法
- Then we also study the effect of string on the dynamical characteristic under the symmetric load and not under the symmetric load as the prestressing is the key making beam string structure the balanceatie system , having large rigidity and embodying the superiority of dynamical characteristic of this structure , this paper studies and conceives how to deteimine the number of the prestressing in each stage of construction and through comparing between the plan of onetime and repeated pulling construction choose the suitable pulling construction plan
并且本文還研究了在對(duì)稱荷載和不對(duì)稱荷載兩種工況下，結(jié)構(gòu)的受力性能隨豎向撐桿數(shù)目、結(jié)構(gòu)垂跨比以及下弦索預(yù)應(yīng)力等參數(shù)改變時(shí)的變化情況，總結(jié)出該結(jié)構(gòu)受力方面的特征，為實(shí)際工程設(shè)計(jì)提供依據(jù)。鑒于預(yù)應(yīng)力是使張弦梁結(jié)構(gòu)形成自平衡體系、具備較大剛度和體現(xiàn)結(jié)構(gòu)性能優(yōu)勢的關(guān)鍵，本文研究和探討了結(jié)構(gòu)施工各階段該預(yù)應(yīng)力大小的確定方法，通過一次張拉與二次張拉方案各項(xiàng)指標(biāo)的比較，選擇適當(dāng)?shù)念A(yù)應(yīng)力張拉施工方案。
