Dow,B.W. Rosen and others evaluated X_c based on the principle of energy,having adopted in the model of composition a fibre of rectangular cross-section,the derived two formulae of Xc in pair hold simplified forms.

The analytical method of concrete bridges for the creeping Secondary inner force of creep has been described in this paper on the basis of the initial strain method and the principle of energy. The stiffness matrix and the force vector of the displacement method are derived, and the creeping effects of the structure under different construction conditions are presented and discussed.

Firstly, The principle of energy dissipation of VDW is discussed and primary influential factors are assessed. It can be concluded that the dissipation performance of VDW is related to the thickness of viscous material, the area of inner steel plate, vibration frequency, the environmental temperature and the properties of viscous materials, which is the most important factor among these and would be the focus discussed in this paper.

Chapter 4 explains the principle of energy dissipation in the view of energy, gives the design code and unified method for energy dissipation struture by two examples, finally states a real engineering which uses the LVED.

According to the reasonable suppose, the three-dimensional problem degenerate to the one-dimensional problem. On the basis of Umansckey's second theory and the principle of energy variation, the one dimensional discretized finite element equation and the corresponding structure model are established for the thin-walled curved box girders with considering the shear lag. .

A geometrically attractive and covariant derivation of the balance laws from the principle of energy balance in terms of this stress is presented.

From the results of tensile, compression, and three-point bend testing of specimens, the parameters of elasticity and strength for an "equivalent" orthotropic body have been determined on the basis of Bolotin's principle of energy smoothing.

Then based on principle of energy equilibrium we propose a global infrared image synthesis model for urban scene, discuss the specific forms for various parts of the scene and compute their surface temperature.

We propose to reconcile these apparently contradictory results by combining the virial theorem and a principle of energy partitioning between energy storage elements in a system with dissipation.

During this period, Helmoltz (über die Erhaltung der Kraft, 1847) showed that the principle of energy conservation may be applied to living systems.

On the principle of energy variation, a stiffness matrix of bar members is here presented, including the influence of shear deformation of the member itself, and taking the nonlinearity and the geometrical nonlinearity of materials into conside- ration. Two kinds of implication of the 《P--Delta》 effect are analyzed. The working condition of the bar member at the elasto plastic stage has been rather comprehensively represented.

On the basis of the principle of energy balance and by means of the concept of substructure, the authors of this paper have conditionally established a set of linear equations concerning the damping parameters of the dynamic model of machine structure. The damping parameters can be immediately obtained by solving the set of equations when other model parameters are known and the value of dynamic stiffness of a certain point on the structure is obtained by testing. The application of this method for identifying...

On the basis of the principle of energy balance and by means of the concept of substructure, the authors of this paper have conditionally established a set of linear equations concerning the damping parameters of the dynamic model of machine structure. The damping parameters can be immediately obtained by solving the set of equations when other model parameters are known and the value of dynamic stiffness of a certain point on the structure is obtained by testing. The application of this method for identifying the damping parameters is illustrated with practical examples. Because multiple parameters can be identified simultaneously by this method, if experimental conditions are satisfied, it may be expected to identify the damping parameters even when the machine struture is mounted and in the condition of operation.

In this paper, a brief explanation of application of the principle of energy for stability analysis of space frameworks is offered. Some foreign data expressions concerned are simplified and to them additions have been made to meet needs of water conservation measure in agriculture. Thus, a better calculating accuracy has been obtained. The computer program compiled based on the predescribed formulation has been proved to accord with results of classical solutions and model tests. It would be a means to...
