The theory and the procedure for calculating the loading stresses in single layered and double layered plain concrete pavements, treatment of vehicle loading and structural boundary condition, regression of results of finite element calculation, rectification of theoretical solution and determining procedure of comprehensive coefficients adopted in newly issued Specifications of Cement Concrete Pavement Design for highway are introduced in this paper

In the environment vibration experiment, the encountered engineering problem is that the test clamp which supports the structure should reflect or simulate the dynamic characteristics provided by real boundary conditions of the structure, which is a dynamic design or dynamic simulation of structural boundary.

Structural boundary conditions recognition and damage diagnosis are of important practical value for the studies of strutural dynamic properties in laboratory. This paper presents a kind of partition combination neural network model based on subnets. Structural boundary conditions recognition and damage diagnosis are realized by the use of static deflections of reinforced concrete beam as characteristic factors.

The structural boundary and structural system of the Cenozoic basin are set up with the aid of experimental contrast and geological generalization method.

Its structural, boundary condition and the complexity that runs environment are designed , are under construction to run the experience of defending , uncertainty and the extensiveness that is concerned with content , can affect the safety of large dams ,so, inspection and detection work get generally to pay attention.

The 3 σ criterion of reliability theory is applied to analyze and compute the structural responses while the structural boundary conditions are stochastic.

The present study hypothesizes that the structural boundary defining process in linguistic organization is a cognitive basis for the production of linguistic expressions.

To deal with the grid movement induced by the structural vibration in the numerical simulation of the FSI problem, a new generation method of the dynamic block- structured grid based on the previous researchers’work is proposed in this dissertation. In this method, the movement of the grid block around the moving structural boundary is combined with the regeneration of the inner-block grid to avoid the aberrance of the grid.

The structural boundary of a caldera, defined here as the outermost limits of subsidence and related deformation including downsag, commonly lies outside ring faults and outside the embayed topographic wall.

The zero level set of the level set function defines the structural boundary.

In this paper, two benchmark problems in structural boundary design are solved using the spectral level set methodology, which is a new approach to topology optimization of interfaces.

The computational advantages associated with the utilization of preconditioned iterative equation solvers are quantified for the reanalysis of perturbed shapes using continuum structural boundary element analysis (BEA).

In the so-called BIE formulation, it is found that more than one type of adjoint functions are necessary, which are defined by different integral equations at complementary points of the structural boundary.

Gaolan Group is a metamorphic series of medium pressure type of regional dynamo-thermal metamorphism that took place at the margin of a basement fault block in Qilian Caledonides.The metamorphism of Gaolan Group revealed three stages of recrystallization and deformation. In the 1st stage of recrystallization greenschist facies mineral assemblages .were formed and the incorporated deformation produced the schistosity So. In the 2nd or the main recrystallization stege, a series of porphyroblastic index metamorphic...

Gaolan Group is a metamorphic series of medium pressure type of regional dynamo-thermal metamorphism that took place at the margin of a basement fault block in Qilian Caledonides.The metamorphism of Gaolan Group revealed three stages of recrystallization and deformation. In the 1st stage of recrystallization greenschist facies mineral assemblages .were formed and the incorporated deformation produced the schistosity So. In the 2nd or the main recrystallization stege, a series of porphyroblastic index metamorphic minerals such as chlorite, bibtite, almandite, staurolite and kyanite were formed in zones displaying a. therma. dome structure. The isogrades are roughly parallel to each other and cut both the stratigraphic and structural boundaries. This indicates that the metamorphism of Gaolan Group was not under the control of structural subsidence or depth of burying,thus it is invalid to correlate the metamorphic grade to the geother_ mal gradient. On the contrary, the metamorphism was rather depended on a local ries of geothcrm, The deformation that corresponding to the main recrystallization had resulted in the tight multiplefold and the major schistosity Si. IE the 3rd or the mig-matization stage, mismatitic granite and migmatitic granitoid gneiss emplaced into the center of the thermal dome. The so-called sillimanite zone was only related to migma tization and had superimposed ou the previously formed metamorphic pattern. The deformatioi that related to this miguiatization stage is characterised by open folds.Theme words meta.norphic rock,metamorpaic zono, metamorphism, deformation event

The equations of the BEM for the inclined boundary problems are derived and analysed in this paper. By the introduction of local coordinates, the transformation relation between, local coordinates and absolute coordinates is established. It makes the BEM simpler and easier when it is applied to the problems of the inclined boundary of structures. Several examples and the stress analysis of dovetail joint of the engine blade show that the results are satisfactory. The results of BEM are more precise than those...

It makes the BEM simpler and easier when it is applied to the problems of the inclined boundary of structures. Several examples and the stress analysis of dovetail joint of the engine blade show that the results are satisfactory. The results of BEM are more precise than those of FEM, particularly in the calculation of .structural boundary stresses.

The structural boundary is represented by a function cf a series of design variables. Then the structural shape optimal design can be represented as a problem of mathematical programming. Three computational examples of shape optimal designs are solved.The three examples are a polygon plate in tension, a bending cantilever and a hollow gravity dam under hydrostatic and gravitational lead. In the computations, recursive quadratic programming is used for mathematical programming and boundary...
