Hexagonal grid cylindrical latticed shell structure is proposed, due to honeycomb structure (although the hexagon structure) is the most effective structure on save the building materials. As a result of the shell structure always with numerous bars, the distribution of internal force and the design of bars often rely on many parameters, likes the span of the structure, the rise-span ratio of the structure, the size of mesh etc., the large scaled finite element software ANSYS parametric design language ANSYS Parametric Design Language (APDL) be used to establish the model of hexagonal grid single-layer cylindrical reticulated shell. The optimization design also was done to found whether the model was a feasibility one. The analysis process shows that the parametric design method provides great convenience for the design of the structure.

In recent years, recycled aggregate concrete has been used in reinforced concrete structures. Concrete structures exposed to chloride environment often encountera premature deterioration due to corrosion of steel reinforcement. In order to avoid unplanned maintenances or repairs, it is necessary to develop a reliable prediction model for the chloride diffusion in concrete. The basic formulation of the transport theory will be presented first and then its application to Recycled Aggregate Concrete (RAC) will follow. Chloride diffusion in RAC is different from the diffusion in regular concrete, because the material parameters of RAC such as chloride diffusion coefficient are different from those of regular concrete. In this paper, a multi-scale and multi-phase model will be developed to characterize theinternal structure of the recycled aggregate with a layer of residual cement paste on the surface of natural aggregate and another layer of surface treatment material on the surface of the residual cement paste. The multi-scale and multi-phase model will also be used to characterize the chloride diffusion coefficient of RAC. The numerical analysis of the diffusion equations is performed by using finite element method.
