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點發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應力混凝土開孔平板的極限承載力進行計算,得出不同開孔參數對應的極限承載力。
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澆混凝土空心樓蓋的極限荷載的計算中,根據理論分析,證明了該方法的可行性。
