Fire-resistance performance of slabs can be improved if the slab strengthened by carbon fiber sheet bonded with inorganic adhesive instead of organic epoxy adhesive with low softening temperature. However, Fire-resistance performance of the strengthened slabs is not understood fully. Considering this issue, finite element analysis is done. Stating from building valid model of finite element, computing results are compared with experimental results, and rationality of the model is verified. Then plenty of parameter analysis is done. Effect of some parameters, such as range of carrying capacity increase by sheet, reinforcement ratio, load ratio to carrying capacity and thickness of slab, on fire-resistance performance of the strengthened slab is analysis. The results demonstrate that thickness of slab is the main factors influencing fire-resistance performance of the slab strengthened by carbon fiber sheet bonded with inorganic adhesive. While, range of carrying capacity increase by sheet, width of section and load ratio to carrying capacity have little influence on it. Slabs, strengthened by carbon fiber sheet bonded with inorganic adhesive, and protected by Thick-typed Fireproof Coating, perform good fire behavior.

Fire-resistance performance of beams can be improved if the beam strengthened by carbon fiber sheet bonded with inorganic adhesive instead of organic epoxy adhesive with low softening temperature. However, Fire-resistance performance of the strengthened beams is not understood fully. Considering this issue, finite element analysis is done. Stating from building valid model of finite element, computing results are compared with experimental results, and rationality of the model is verified. Then plenty of parameter analysis is done. Effect of some parameters, such as Range of carrying capacity increase by sheet, reinforcement ratio, load ratio to carrying capacity and width of section, on fire-resistance performance of the strengthened beams is analysis. The results demonstrates that reinforcement ratio and load ratio to carrying capacity is the main factors influencing fire-resistance performance of the beam strengthened by carbon fiber sheet bonded with inorganic adhesive, While, range of carrying capacity increase by sheet and width of section have little influence on it.

Gravity abutment widely uses for substructure part of the bridge structure. For many reasons, there are many damages take place in the parts of abutment. The objective of this study is to evaluate the strengthening effects on the performance of highly structure of Gravity abutment. The results of damage inspection show that these damages are very serious in the direction of height and width of the abutment structure. Therefore, there is need to strengthen the abutment structure to improve the carrying capacity. There are two experimental models. The first model uses one ring of carbon fiber sheet and the second uses two rings of carbon fiber sheet .The results of experimental show that there are good effects when using carbon fiber sheet strengthening method.

The developments of electromagnetic wave shielding materials are strongly required because the malfunction of electronic equipment, mobile phone and wireless LAN avoids. In this study, it was investigated that the electromagnetic shielding effectiveness of carbon fiber sheets were enhanced by the ferrite which was coated by the microwave hydrothermal process. For coated carbon fiber sheet, the effects of ferrite and lamination of carbon fiber textile on the electromagnetic wave shielding effectiveness were discussed. In the range of frequency (100 – 1 GHz), the electromagnetic wave shielding effectiveness was measured by using TEM-Cell. The electromagnetic wave shielding effectiveness was greater for the coated carbon fiber sheets than for the uncoated carbon fiber sheets. When the insulation film was located between two carbon fiber sheets, the electromagnetic wave shielding effectiveness increased.

This paper takes Huzhou Baimitang Bridge as an engineering example, expounds the common diseases of through pre-stressed truss arch bridge and their causes. It uses structure calculation software to optimize the reinforcement methods of components, such as arch rib, diagonal brace, tie beam, etc. The results show that pasting steel for arch rib, diagonal brace and pasting carbon fiber sheet for tie beam can effectively enhance the stiffness and the carrying capacity of Baimitang Bridge. The reinforcing methods are good for reference of other similar engineering projects.
