The some Concept design’s typical characteristics of Building structure Ting Ding1,a Qiwen Li 2,b Shengguo Ding 1,c 1College of Civil Engineering and Architecture, Guizhou University, Guiyang China 2 Mingde college, Guizhou University, Guiyang China adthjy@163.com,b liqiwen0520@163.com,c 648869109@qq.com Keywords: design Internal force, conceptualization Abstract: The characteristics of effect are expounded for different structure under the specific load.
After summing up a lot of engineering structure calculation based on the results of different structure, some typical characteristics of load effect can be reduced , usually these typical effects called conceptual design features.
In the actual engineering, boundary conditions may be made completely different constraint: plate edge and beam rib end may be restricted by the deflection for perpendicular to the surface, the restrictions of rotation for the tangential direction along the boundary, and the restrictions of rotation for perpendicular to the boundary.

Risk Monitoring System for Tunnel Boring Machine and Its Application in Risk Prediction and Management Hua JIANG1,2, a, Yusheng JIANG1,b and Jinxun ZHANG2,c 1 School of Mechanics & Civil engineering, China University of Mining & Technology, Beijing, CHINA 2 Postdoctoral Programme, Beijing Urban Construction Group Co.
Accordingly, RMSTC has been developed and successfully applied in metro engineering.
Among them, system display interface, engineering progress, cutting wheel and screw conveyor belong to display interface, the major functions are to display various parameters, engineering progress and the relationship between engineering progress and significant risk evaluation engineering.
l The system can display engineering progress and analyze risk management information timely, it also provides convenient for the users to analyze the distribution situations and mechanical mechanism of major risk engineering, and proposes the keys in management and controls.
Fig. 4 Display interface of information management system Engineering application Since RMSTC is developed, it has been widely used in many city’s underground tunnel engineering of China, such as Beijing, Tianjin, Guangzhou and so on.

This design project has been tested on marine buoy and the accuracy of the model is splendid for most engineering projects.
In engineering practice, the charge current is about 0.1C of the battery pack capacity.
