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。
( 3 ) using yielding line theory , we educed ultimate capacity of slab - column connection which was bend destroy under vertical load , vertical load and unbalanced bend in the text ( 3 )利用屈服線理論,推導(dǎo)出豎向荷載作用下、豎向荷載和不平衡彎矩共同作用下板柱節(jié)點發(fā)生彎曲破壞時的極限承載力。
Secondly , the writer carried out the calculation on prestressed concrete slabs with openings by yield line theory and got the changes of limit load of openings of different size , different place 然后,筆者采用屈服線理論對預(yù)應(yīng)力混凝土開孔平板的極限承載力進行計算,得出不同開孔參數(shù)對應(yīng)的極限承載力。
3 . the ultimate bearing capacity of such floor is worked out by applying yield line theory to thin - wall core box cast - in - site concrete hollow floor . and it is proved to be feasible according to the theoretic analysis 3 、將板的屈服線理論引入薄壁箱體現(xiàn)澆混凝土空心樓蓋的極限荷載的計算中,根據(jù)理論分析,證明了該方法的可行性。
