This study proposed the sports training auxiliary system design concept based on the characteristics of cloud computing and needs of modern sports training. The paper illustrates the key technology of system of body frame structure, infrastructure services, platform management, intelligent service, etc. The system not only to the popularization of computer-assisted training, improve the effect of training plays an important role, and can obviously improve the different regional sports resources is not balanced, the unequal status information.

The research of optimization for steel truss bridge based on reliability theory is discussed by using optimization and reliability module in ANSYS software. The reliability design method is elucidated by comparing the results of common design with general optimization and reliability optimization.
