The energy law of yield line theory was applied to the theory of “ resistance unit ” of flat slab strengthening analysis 屈服線理論能量法用于無梁板加固分析的“抗力單元”理論、及該理論應(yīng)用于加固分析的可行性。
It has been found out that using a prestressed concrete flat slab floor can decrease the thickness of the floor slab , improve forced property and service functions of the structure , and so as to save materials , reduce cost and prevent the cracks of shrinkage and temperature 采用預(yù)應(yīng)力混凝土無梁樓蓋可以降低樓板厚度,改善結(jié)構(gòu)的受力性能和使用功能,而且能節(jié)約材料,降低造價(jià),防止收縮和溫度裂縫的產(chǎn)生。
It is keeping the reasonable principle in deciding flat slab type . we choose the most suitable type to satisfy application demand and to save investment through the technical and economical indexes for these type of floor stmctures and understanding every type ' s sphere of application , advantage and disadvantage 通過對(duì)幾種樓蓋的受力及經(jīng)濟(jì)分析,了解他們各自的適用范圍和優(yōu)缺點(diǎn),選擇最適宜的型式,西南交通大學(xué)碩士研究生學(xué)位論文第頁(yè)滿足使用要求,又節(jié)省造價(jià),并為以后工作提供了參考的可能。
