At present domestic for various structure reinforcement method are many, these methods each have its applicable condition, which require us to combine with the actual engineering situation, the comprehensive analysis of the technical economy, fully consider various methods of the implementation of the degree of difficulty, construction and other factors, however, and the investment decision-making, take optimal optimize project, making reinforcement can guarantee the safety of the structure, and the economic and reasonable.The connotation of aseismatic reinforcement is structural reinforce rather than single component reinforcing, so in the reinforcement design, the first consideration should be given to the structure integrity, as much as possible to retain and using original components, reduce unnecessary dismantled and replacement, make reinforcement measures play, avoiding "comprehensive effect of instant gratification, JiaoTongYiJiao" component reinforcement measures. Strengthening technology because its technology to mature, cost low cost, construction moderate scale, construction period shorter, more and more excellent characteristics such as the favored by building unit. At the same time, along with the market economy in China in recent years, the building structure the vigorous development of rigid scale expanding demand and little input outputs of the contradiction between investment concept relatively sharp rise. The old building add layer, old factory building reinforcement and earthquake reconstruction, these and the development of social economy, therefore, reinforcement is directly related to the development and application of technology theory is increasingly mature. Rebuilding less than new can faster recovery funds, funds, the more effectively promote national economic rapid development, application and development of strengthening technology theory is significant social meaning and obvious economic benefits for the 121m.This paper is complied with the trend of The Times, and according to my previous work practice, mainly HuaYin city commercial building with shaanxi mentioned in the reconstruction project of reinforcement engineering, the principle of reinforcement technique, workflow, strengthening the basic structure assumption made a preliminary calculation, the paper introduced "increase compared in detail section reinforcement method" and "paste steel reinforcement method", " prestressed reinforcement method", "change stress system reinforcement method" "extension-story consolidation method" and "pasting CFRP reinforced law" and other reinforcing the principle of method, main characteristics, the reinforcement design and of normal section of the bearing capacity of the inclined section computation theory, the construction technology and the matters needing attention. At the same time use the computer software of the CFRP reinforced concrete frame beams performance analysis, give CFRP reinforced concrete frame beams of the numerical research methods. By comparison with FRP strengthened beams reinforced beam of bearing capacity, author analyses tension capacity significantly improve reinforced beam, the result of the experiment results at home and abroad and have done corresponds with the expected objectives.
