求翻译：之后用弯矩二次分配法和D值法分别进行内力计算，求出以上各荷载作用下的结构内力（弯矩、剪力、轴力）。是什么意思？

After the force calculation, the Moment Distribution Method and d values ​​were obtained under the above load structure of internal forces (bending moment, shear, axial force).

After 2 times with bending moment D value distribution law and law in force calculation, respectively, each of the above loading within the structure of the force (curved shaft torque, shear, and competitiveness.

Afterwards carries on the endogenic force computation separately with the bending moment two methods of distribution and the D value law above, extracts under various loads function structure endogenic force (bending moment, shearing force, axle strength).

Later method of moment quadratic distribution method and d-value calculation for internal force respectively, seeking out of the structure under load inner force (bending moment and shear force and axial force).
