Reinforcement Technology On Reinforced Concrete Building Structures And Its Application In Engineering

At present the main structure form of buliding construction is still in the reinforced concrete, due to design flaws, construction quality, functional change, improper maintenance and other reasons, cause the building during use structural bearing capacity can not meet the normal requirements, therefore carries on the necessary building structure reinforcement so that it can continue to use is very important. This thesis based on the current conventional reinforced concrete structure reinforcement method analysis and abroad, combined with COFCO Great Wall Chateau Sungod upgrade project, discussed the reinforcement design methods and strengthening strategic analysis of reinforced concrete structures. The main contents are as follows:(1) For the most commonly used reinforced concrete structure reinforcement technology at home and abroad are described, analyzed and evaluated the advantages and disadvantages of its application prospect usual reinforcement technology. For increasing non-prestressed reinforced concrete building structure cross-section reinforcement method, outsourcing steel reinforcement method, paste method of steel reinforcement and paste CFRP reinforcement law, focusing on analysis of the secondary load structural reinforcement and bonding surface after breaking strength problem.(2) The characteristics of the actual engineering, design and calculation principles for strengthening, strengthening the basic ideas designed to determine the reinforcement and reinforcement of a comprehensive program of measures elaborated. Design of reinforced concrete structural reinforcement, should be based on the original structure construction drawings and related design specifications, re-checking of the original structure, to fully consider the secondary load problems after structural reinforcement and new and old materials combined with surface treatment, to ensure the structure Under the premise of Reinforced bearing capacity, the situation appears to prevent excessive strengthening.Reinforced concrete structure reinforcement technology will ensure maximum use of security structure, prolong the using life of the buildings, bring good social benefit and economic benefit, and has very important realistic significance.
