PAGE PAGE IV Abstract Since the founding of the PRC ，especially after the reform and opening up, the development of Chinas construction industry rapidly. Currently the construction industry has entered a period of unprecedented prosperity, more and more new requirements for the quantity, quality and use of the building functions: on the one hand, a variety of new materials and new techniques constantly emerging; on the other hand, the construction industry is faced with how to reinforce the existing building structure and retrofit. However, at present a lot of building structure reinforcement exists blindness, resulting in strengthening purpose is not clear, the construction method is not scientific. Therefore, research the impact of the reinforcement of the building structure, the reliability of various factors to determine a better, more economical, more rational reinforcement methods, it is very important to improve the efficiency and reliability of the reinforcement of the building st ructure. In this paper, the Guangzhou region of a teaching building as the research object , to carry out the on-site detection of steel bonded reinforcement, according to the detection results of reinforcement structures are proposed; theoretical analysis bonded steel reinforcement reinforced concrete rectangular section flexural beam; analysis the before and after reinforcement the of structural components resistance model and load model, to obtain the statistical parameters of basic variables before and after reinforcement ; According to reliability theory, establish reliability analysis methods of structural reinforcement member, analysis and calculation of the reliability of structural members before and after reinforcement. First of all, field testing of a teaching building in Guangzhou area, mainly for the foundation, the upper structure and the appearance of the building structure and enclosure structure inspection. According to the testing results of structure reinforce
