Abstract: This paper analyzes the normal section capacity of the reinforced concrete paste with
CFRP.
Resene glue materials and carbon fibers are pasted on the surface of concrete structure, in order to achieve the purpose of reinforcement of structural components and the improvement of mechanical properties.
In order to meet the requirements of safety, we used the CFRP materials to reinforce the original structure.
After theoretical calculations, we get the following conclusions: (1) The experimental results show that reinforced concrete beams paste with CFRP have significant reinforcement effect, and the ultimate bearing capacity has been improved after reinforced with CFRP materials

The paper discusses the operation mode of charging system with polymer insulation materials, risk assessment and cost analysis of electric vehicle charging mode.
Therefore, it should analyze the operation mode and cost of electric vehicle charging system with polymer insulation materials.
Conclusion Charging cost and convenience decides the development scale and trend of pure electric vehicle charging system with polymer insulation materials.

Due to harmful effects of lead, time degradation
of glass and because of many kinds of local raw materials for glass production especially sand,
colorless lead-free high refractive index glasses were prepared by using local raw materials.
Conclusions In conclusion, the lead-free high refractive index glasses are one of the environmental friendly materials.

Model of calculation
On the basis of the past experience and the practical conditions, some hypothesis are established for the FEM model as follow: (1) the stress-strain relationships is satisfied to the basic hypothesis of plain strain problem; (2) the anchor bolt and lining are belong to elastic materials, but the rock mass and soften joints are considered as elastic-plastic medium; (3) the normal of the isotropic surface is orthogonal to the axis of underground opening.
The deformation modulus of interfaceequals to 500kpa, equals to 400kpa andequals to 50000kpa, other material parameters are shown in Tab.1.
