"For example, the design of the steel structure is the granary cylinder reservoir in the structure of a special application is primarily used for storage of cement powder form solid particles, large storage structure on the strength and stiffness of steel structures such areas have high demands, mainly Leung is at the bottom plate and the strength and stiffness of the calculation, in order to ensure the reliability of the structure, we need a structural stiffness and strength of the analysis.
