The research presents that, this system can carry out the integration of CAD/CAE in early auto body development, enhance the efficiency of project selected and the reliability of structure designed. It has good flexible and make design efficiency improve.
According to complexity of stress of construction platform,it introduces selection of structural plan、sampling method of load and construction method of structure,which has some reference.
The result shows that this method has better effect for prediction of the seismic property for the frame structure of bottom story and is suitable for application in the scheme selection of this kind of structure.
Through the analysis of VE and LCC, a series of method and model on the selection of architecture scheme, structure scheme, economize energy, and selection of equipment type is put forward, and the applications of AHP in comprehensive evaluation of design scheme is studied.
This paper described the method of determining optical parameters and the selection of overall construction program of the optical systems, and also presented constitutiton of optical systems, and requirements and characteristics of each branch system.
This paper analyses quantitatively the ballistic errors of electromagnet control gyrocompasses by virtue of a computer and confers on some general methods for decreasing and compensating the ballistic errors by use of computer aided analysis. Some instructive opinions are consequently suggested to select the period and constructions for electromagnet control gyrocompasses.
This paper briefly reports the results of engineering seismic risk analysis and of the research in earthquake groud motion parameter, dynamic behavior and earthquake resistant behavior of hydraulic structure in the Three Gorges Project. The results of analysis show that dynamic behavior of the Three Gorges Project dam is better than usual gravity dams. This dam type is favourable for improving its earthquake resistant behavoir. Other hydraulic structures of the project can also satisfy the requirements of d...
