Third,according to an example,the influence on soil displacement stress etc under harmonic vibration load induced by infiltration coefficient and loads frequency variation is studied numerically in dissertation.

The computation and comparison of the load induced bending moments of beams on two different foundation models, which are an elestie layer in sticky conjuction with a rigid stratum and an elastic layer in smooth contact with a rigid stratum, show the difference between the computational results of two foundational models.

Dynamic finite element analysis shows that the beam rebounds severely under the blast load induced by the low drag general purpose bomb and the resistance of the negative moment as well as the capacity to resist tensile force at the support is insufficient.

Based on the numerical simulation of vertical vibrating load induced by high speed train with excitation function,dynamic response of large cross-section tunnel under the vibrating load has been analyzed by elastoplastic finite element method;

Conclusion:It showed that negotiated care could lessen the volume load of CAPD patients, lower their blood pressure, reduce the use of hypotensive drugs and prevent volume load induced cardiovascular complications of CAPD patients.

The paper is concerned with a specific problem in the study of an infinite beam embedded in a two-parameter elastic foundation (Vlazov-layer) under the equivalent load induced from a surface load moving normal to its length.

Embedded beam under equivalent load induced from a surface moving load

We record this load induced growth to yield phosphate islands which are significantly smaller but harder than those grown by thermal activation alone.

The life-load characteristics that we record in these experiments, we argue, can only be explained if there is a load induced growth of the deposited film during sliding.

It thereby exploits the variation in disk load induced by VBR-encoded objects and the decrease in client load by caching.

An experimental investigation on liquid sloshing in rectangular tank models has been carried out in the Ship Hydrodynamics Laboratory of Shanghai Jiao Tong University. This paper gives the hydrodynamic characteristics of dynamic loads induced by the liquid sloshing, such as the natural frequencies, the pressures and unstable phenomena. It may be useful for designers.The results obtained has been compared with that from the nonlinear sloshing theory used by FEM[1] and the experimental data given by M. Higuchi[2]....

An experimental investigation on liquid sloshing in rectangular tank models has been carried out in the Ship Hydrodynamics Laboratory of Shanghai Jiao Tong University. This paper gives the hydrodynamic characteristics of dynamic loads induced by the liquid sloshing, such as the natural frequencies, the pressures and unstable phenomena. It may be useful for designers.The results obtained has been compared with that from the nonlinear sloshing theory used by FEM[1] and the experimental data given by M. Higuchi[2]. It can be seen that the results given in this paper are satisfactory and the formulae presented in this paper can be used as reference in estimating the natural periods of liquid sloshing and the magnitude of dynamic loads induced by the movement of liquid in rectangular tanks.It is shown that the experimental value of natural frequency in rectangular tank without the internal structures is about 1.13 times the theoretical value.The authors point out that the impact pressure at the deck corner and the noises caused by the sloshing load should be considered.In order to find a method to avoid the serious sloshing, the experimental investigation about the liquid sloshing in tanks with internal structures such as wash bulkhead, deep deck beam and bottom web frames has been made and their effectiveness of avoiding t he serious sloshing has been discussed. The results show that the deep deck beam is an efficient and economical structure if its lower edge immerges in the free surface of liquid.

In this paper, the Fouries Transform Method, as one of the solutions problems of elasticity, is used to solve the elastic layer under the action of vertical force on its surface. The elactic layer has a finite depth and sticks on a rigid stratum. Thereby a practical foundation model for the analysis of foundation beams on elastic layers of finite depth is developted. The computation and comparison of the load induced bending moments of beams on two different foundation models, which are an elestie layer...

Through the analysis of previous test data and practical experiences in crack control for partially prestressed concrete structures, it is found that the width of crack may be rationally controlled by the stress increment in reinforcing steel. Based on the test results of six unbonded partially prestressed concrete beams under static or fatigue loading, the development of cracking width and residual stress is studied, and a formula for calculating the crack width after N cycles of repeated loading...

Through the analysis of previous test data and practical experiences in crack control for partially prestressed concrete structures, it is found that the width of crack may be rationally controlled by the stress increment in reinforcing steel. Based on the test results of six unbonded partially prestressed concrete beams under static or fatigue loading, the development of cracking width and residual stress is studied, and a formula for calculating the crack width after N cycles of repeated loading is presented. Some permissible values in the table are placed on the load-induced stress increment in the reinforcing steel and prestressing tendons for restricting crack width in design.
