On the basis of the energy variation principle,the generalized force corresponding to the shear lag displacement in shear lag analysis of the box girder is clearly defined and is called the shear lag moment.

The generalized force of disc applied to shaft including gyroscopic effect is determinated in this paper by using Euler angle of fixpoint rotating kinematics and Lagrange equation, for the dynamics response analysis of a system.

According to relations between generalized forces and generalized displacements, convolution are performed between the governing equations of initial value problems in the primary space and the corresponding virtual quantities, and results are added algebraically.

In view of the problem of working internal forces caused by the elasticity of parts and the damper between parts in the firing process, based on the basic concepts of mechanics, this paper presents the deduced formula for the general force of working internal forces.

Based on the theoryof general suction and general effective stress of remolding non-saturated soil,the mechanism of embankment subsidence is analyzed,and a theory of two-step settlement is presented.

A fuzzy reliability calculating model is given again based on function which includes generalized stress and generalized strength.

Based on the similar equations of the elastic-plastic model theory and the plastic deformation theory,this paper presents,according to the plastic model theory and the relations between generalized stress σi and strain εi curves of prototype materials,the resilience test model of elastoplastic stress analysis with .
