Research On Reinforcement Scheme Of A Frame Structure

Since the founding of new China, concrete structure in China has entered a stage of rapid development, reinforced concrete structure with material sources, fire properties, and can be higher, and thus become the main structure of the building on the market in various fields. But due to the reinforced concrete structure at the same time has a significant early strength, low tensile force and structure low, so in practical engineering, structural design and construction sequence errors, accidental loads or other reasons, can lead to reinforced concrete structures during construction and use during the inevitable cracks. Crack production and development will directly affect the service life of the bearing capacity of the structure and even can cause serious economic losses and casualties.Therefore, the crack should be comprehensive and accurate analysis of the structure, grasp the structure of the causes of stress and crack. For repair and reinforcement measures can continue to use the buildings, structures, should timely adopt reasonable measures to deal with the cracks and structural reinforcement of key parts.However due to the lack of reinforcement in reinforced concrete structure systems, comprehensive research and normative management, at the time of consolidation may be due to the structure change and reinforcement design and construction quality problems such as defective, unable to maximize structural strength and safety, caused greater damage even to the main structure.On problems in design and construction of reinforced concrete structure, based on the actual case, first of all analyses the causes and mechanism of cracks, summarizes the methods of fracture treatment. A square in the construction process, analyses the causes of the cracks in some structures, of frame structure using finite element software SAP2000 stress analysis of the local, and presented based on analysis of crack treatment and structure reinforcement. Ultimate combination of engineering, rational optimization scheme, and has been used in actual projects, achieved good economic and engineering benefits.This systematic engineering processes and methods, provide a basis for engineering and construction, while this study uses a mechanical analysis combined with practical methods of analysis, which provides some guidance for similar projects.
