The Research On The Application Of Strengthening Technique To Concrete Structure Of Building

The concrete structure of the buildings has become the fastest-developed and the most widely-used structural system in the field of building in the 20th century. However, in the use of this structure,various kinds of structural safety hazards often occur owing to the building's aging, natural disasters and damages caused by human beings etc.Some newly-built projects have technical and managerial problems in inspecting,designing and constructing, thus posing security threats in the process of construction or at the beginning of the construction. If not taken measures to reinforce, they may lead to serious accidents.How to take effective measures to recover the damaged buildings is an important subject for technical professionals to research and is the aim of this thesis.First,this thesis expounds the significance of reinforcement based on the characteristics of reinforcement project.It gives comprehensive analysis of the reinforcement conditions and methods of the concrete structure components like beam,floor,pillar and etc.By comparison, it summarizes the characteristics and applicability of some common reinforcement methods.Secondly, this thesis introduces the calculation methods of normal section and inclined section bearing capacity in each reinforcement formula, which provides calculating basis for the buildings' reinforcement and reconstruction.Thirdly, reinforcement structure belongs to members of loading in two stages,keeping new and old concrete structure working together is the key to concrete reinforcement result.Fourthly, the author of this thesis combines the reinforcement project he took charge of to introduce the procedures of reinforcement projects and provide different reinforcement methods and construction technology, which is helpful to concrete structure reinforcement.
