Primary Study of Applicability of Plane-section Assumption of Shaped RC Columns

Adopting the element SOLID65 and LINK8 in the general finite element analysis software ANSYS and fiber model beam-column element based on finite element flexibility method respectively, the comparative analysis of the cross, L and T-shaped RC columns under compression, bending, shear and torsion with flange width-thickness ratio of 4:1 is carried out. The applicability of plane section assumption in the nonlinear analysis is discussed primarily, which shows that it is feasible on the whole for shaped RC columns with flange width-thickness ratio equal to or smaller than 4:1.     

Structural Analysis and Discussion of Wide -stayed Bridge Basket

Based on a cable -stayed bridge girder as an example, the structure and function, the operating principle and calculation model of the main elements of the Basket of wide - stayed bridge were described in detail. A further discussion was carried out on the Basket of Cantilever construction of the main beam in the structure.     

FEM on Coupled Hydromechanical Dynamic Response of Geogrid Reinforced Soil Retaining Wall

Geogrid reinforced soil retaining wall(GRSRW) is composed of panel,geogrid and soil,its coupled hydromechanical structural characteristics are increasingly emphasized in practice.In this paper,based on the characteristics of the reinforcement-soil interaction,the grogrid and soil around it with a definite thickness were regarded as a kind of composite material with strain-compatible condition.A saturated porous media model was introduced to simulate the soil and reinforcement-soil composite material hereby and the mathematic model for numerical analysis on structural characteristics of GRSRW was built up.The FEM equations were deduced from the standard Galerkin procedure,resolving these equations,we can gain the relevant dynamic response of saturated GRSRW.     

Accomplishment of Elastic-plastic Analysis in Geotechnical FEA

In order to realize elastic-plastic analysis in geotechnical FEA, in this paper, firstly, the method how to realize elastic-plastic analysis in Super-Sap is discussed. Then, this paper stresses to introduce the principle and the steps used to achieve the accomplishment of elastic-plastic analysis in Super-Sap. Finally, an engineering practice is given to prove that the geotechnical FEA elastic-plastic analysis and visualized post-processing can come true by it rapidly.     

Orientation of Aim Client in Real Estate Development Based on EXCEL

In order to subdivide the market during the process of project planning and orient the group of client, then determine the sale price; on the condition that the traditional orientation procedure cant grasp the payment capability of the aim client, the anthors can adapt the powerful finance analysis ability of EXEL to design the procedure of determining the purchasing power and payments ability of the aim client, and shape a set of orientation system based on quantitative analysis method. The result is, the character of the aim client can be grasp accurately depend on this orientation system, and providing a scientific gist for the accurate orientation of price and lowing the risk of investment etc.     

Concrete Evidence Reseach to the Aacepting Insurance Ability of China''s Non-life Insurance Companies

Owning to the ability of accepting insurance enough,it is the foundation for insurance companies to operate in a long-term and steady way,a method to develop sustainably,a reflection of an insurance company's comprehensive competition ability and also a premise for an insurance company to realize developing strategy.Accepting insurance ability is very important in the development and strategic planning for an insurance company.The quantitative analysis is used to analyze the ability of accepting insurance of our country's insurance companies,in another word,the factor(analysis),which belongs to the analysis of diverse statistic,is used.Using the method to give a concrete evidence analysis to the ability of accepting insurance of our country's non-life insurance companies,so that the insurance companies can understand very well to the advantages and disadvantages of the ability of accepting insurance to each other,and as well as supplying a strategic reference for the insurance companies themselves to make decisive planning.     

Application of Principal Component Analysis on Workable Competition Evaluation

The effective competition is an effective organizational form of the industry in modem market economy. It is a form accompanied with large - scale production and vigor competition. The analysis of effective competition has been the focus that people have paid close attention to it very much all the time. It is a basis of industrial policy, on the basis of the former research, the aufhors bring out 9 indexes according to the actual situation of our country, then take automobile trade as an example, we analyze the automobile trade with principal component.     

New Method to Study In-situ Stress of Rock Mass by AE and Structure Analysis of Rock Mass

In this paper, the authors adopt a method of structural analysis and stereography in combination with acoustic emission Kaiser Effect test in laboratory to find out the main direction of initial stresses. For overcoming the shortcomings of Kaiser effect by comparing it with traditional methods of measuring in-situ stresses, it is shown that this method is simpler, more economical and convenient for a large number of measurements and for studying the law of changes of regional in-situ stresses.
