一、本程序按有限单元法中的变位法编制,采用矩形单元体,其位移模式为:φ=α_1+α_2x+α_3y+α_4x~2+α_5xy+α_6y~2+α_7x~3+α_8x~2y+α_9xy~2+α_(10)y~3+α_(11)x~3y+α_(12)xy~3计算公式详见文献[1]第七章二节和四节。二、本程序采用修正平方根法解线性方程组。三,本程序用来计算带桩分离式坞底板时,假定桩头与板为铰接,桩反力作用在结
First, the program according to finite element method in the preparation of the displacement method, the use of rectangular unit body, the displacement mode: φ = α_1 + α_2x + α_3y + α_4x ~ 2 + α_5xy + α_6y ~ 2 + α_7x ~ 3 + α_8x ~ 2y + α_9xy ~ 2 + α_ (10) y ~ 3 + α_ (11) x ~ 3y + α_ (12) xy ~ 3 The calculation formula can be found in Chapter 1, Section 2 and Section 4 of [1]. Second, this procedure uses the modified square root method to solve linear equations. Third, the procedures used to calculate the separation with the dock dock floor, it is assumed that the pile head and the plate is hinged, pile reaction force in the knot
