In Reinforced Concrete Frame Superimposed Layer Transformation Reinforcement Method And Applied Research

With the high speed development of enterprise, while the original construction facility is unable to satisfy the operation requirements and large-scale new construction will take massive funds and time of enterprises, renovating the existing construction will be a relatively economical choice. Reasonable reconstruction of old buildings can not only speed up the buiding process to save the construction funds, but also reduce the adverse factor of land resouce strain, large amount of funds used, long period of recover and so on which are brought from largr-scale new construction. It will be good for enterprise itself and also of significance for the whole society and contry.This paper based on the existing add layer theory, use the available technology tools, raise the design method of analysis and comparison of the overall transformation, heightenting reform the reinforced concrete frame of tantalum powder institution. Achieved good respond and accmulated reinforcement experience. The main work follows:①General described the current main reinforcement technology, adding layer design principle, the force characteristics of reinforced structures, and basic calculations assume of strengthing structure. Systematically summarize bearing capacity calculation and design theory of"increase cross-section reinforcement method", "outsourcing steel reinforcement method" and "stick steel reinforcement method".②As for the heightening reform project of tantalum powder institution, combined with related theory to study how to analysis, process and reinforcement the structural transformation caused by the change the whole structural analysis, proposed a more comprehensive rehabilitation program.③The use"SATWE-8"to analyse overall performance before and after structural modification, and reinforcement components internal forces such as the difference, come to transform the original structure of the overall performance of weakening, internal force redistribution and other changes in law.④Components that need to be reinforced with the use of units requested, a reasonable choice for concrete reinforcement reinforcement method.⑤The use"SATWE-8"to check the result of structural reinforce design, reanalyse transformation, the structure of the overall performance, components and other aspects of internal forces and the reinforcement re-analysis of structural transformation from the theoretical evaluation of the effects of reinforcement.⑥Summarize the results of the reform, the equal strength experiental substitution factor, the accumulation of similar projects for the future transformation of experience.
