The existed railway bridges in China are either single-track line bridges or double-track line bridges. Checking fatigue to double-track line steel bridge, we should take two trains possibly passing bridge at the same time into consideration, and fatigue make cumulated damage contain with this loading effect.

The numerical simulations show that the preloading along the orthogonal direction would cause stress degradation in soils and induce orthogonal loading effect.

The truth structure destruction is decided by the combination action of load breadth and circular load effect explains preferably effect three essential of earthquake motions to structure destroy.

This paper presents an alternative method which couples the thin-walled beam finite element method (FEM) and the two dimensional boundary element method (BEM) to solve the bending-torsion coupling vibration of ship hull in water.

By using a kind of accumulative damage model that mirrors the effect of cyclic loading and maximum deformation, the damage evolution of steel reinforced concrete(SRC) frame columns(batten plate/lattice type and full web type) under earthquake is analyzed and its seismic behavior further discussed.

Based on the influence surface of the bridge and the fluidity and series of highway live load,the C language program was written and the effect due to live load superimposed on the influence surface was considered, the program model includes:①trigonometry formed from the influence surface;

②according to the rules and the grade of loads to fix a group of vehicles, the effect of loads of the fixed vehicles and the maximum value of each subdomain was calculated;

The loading effect in the vertical and horizontal position time series is identified, however with significant disagreement in amplitude compared to ocean loading model predictions.

In order to correctly model this ocean loading effect near irregular coastal areas, a high-resolution coastline is required.

The Loading effects of the box type microwave applicator has been stutied.An general analysis is made first with regard to an arbitrary load, followed by calculations concerning two concrete cases,and formulae for the frequency spectra of the loading are obtained. The loading effects of box type microwave applicator are mainly:1, The shift of the resonant frequency;2,The degeneracy splitting;3,The redaction of quality factor;4,The variation of input impedance.These loading effects lead to remarkable changes...

The loading effects of box type microwave applicator are mainly:1, The shift of the resonant frequency;2,The degeneracy splitting;3,The redaction of quality factor;4,The variation of input impedance.These loading effects lead to remarkable changes of the working state of the applicator,and therefore have to be reckoned while designing or using the apparatus.The designing and calculating methods based on the resonant spectra of unloaded case prevalent in the present literatures,home or foreign, are considered by the auther to bo at least lacking of generality.The calculated rersults of the unloaded cases cannot match with the practical working state of the applicator.A more strict design calculation is bound to include the loading effects. A brief discussion of the practical applications of the proposed calculation methods concludes this work.

Immediately before an earthquake the pressure water layer may produce momentary flow under the action of pulse—shaped earthquake force. In the light of the unsteady flow theory the authors proposed a mechanism to calculate the theoretical curves of the water level drop and the flowing rate of the underground water in the abnormal boreholes according to the radial symmetrical flow model so as to imitate the typical observational curve of the uprising of well water.

Immediately before an earthquake the pressure water layer may produce momentary flow under the action of pulse—shaped earthquake force. In the light of the unsteady flow theory the authors proposed a mechanism to calculate the theoretical curves of the water level drop and the flowing rate of the underground water in the abnormal boreholes according to the radial symmetrical flow model so as to imitate the typical observational curve of the uprising of well water. The developing process of this mechanism requires the formation and vanishing of a funnelshaped distribution of ground water level. Therefore, it is necessary to make further calculations on the theoretical abnormal curves of vertical deformation on the ground surface, gravity, geoelectricity and geomagnetism. These phenomena are all related to the growth and decay of the funnel. Before a strong earthquake, lots of abnormal points of uprising of well water type are generated. At the same time, due to variations of the ground stress and dformation field, the balance state of ground water distribution is disturbed and subsurface fluid flows along faults and crevasses. Thus, geophysical effects more complex than radial symmetrical flow will be produced. This is a shallow layer mechanism of short—term precursors.

A two-surface constitutive model, which considers the effects of cyclic hardening / softening, plastic strain amplitude history and nonproportional cyclic loading, is presented. In the model, the evolution equations of limit and yield surfaces are introduced, the nonproportionality of cyclic strain paths is denned, and a rational method to determine the modal parameters is proposed. The predictions of the model, for 42CrMo steel with quenched and tempered treatment, agree with the experimental results very well....
