Grade: 2008 Name: YouYi Specialty: Civil Engineering (Geotechnical engineering direction) Instructor: bohuZhang School of Civil Engineering and Architecture 2012-4 Concrete structure reinforcement design Abstract:structure in the long-term natural environment and under the use environment's function, its function is weaken inevitably gradually, our structural engineering's duty not just must finish the building earlier period the project work, but must be able the science appraisal structure damage objective law and the degree, and adopts the effective method guarantee structure the security use, that the structure reinforcement will e an important work. What may foresee will be the 21st century, the human building also by the concrete structure, the steel structure, the bricking-up structure and so on primarily, the present stage I will think us in the structure reinforcement this aspect research should also take this as the main breakthrough direction. 1 Concrete structure reinforcement Concrete structure's reinforcement divides into the direct reinforcement and reinforces two kinds indirectly, when the design may act according to the actual condition and the operation requirements choice being suitable method and the necessary technology. the direct reinforcement's general method 1)Enlarges the section reinforcement law Adds the concretes cast-in-place level in the reinforced concrete member in pression zone, may increase the section effective height, the expansion cross sectional area, thus enhances ponent right section anti-curved, the oblique section anti-cuts ability and the section rigidity, plays the reinforcement reinforcement the role. In the suitable muscle scope, the concretes change curved ponent right section supporting capacity increase along with the area of reinforcement and the intensity enhance. In the ponent right section ratio of reinforcement not too high situation, increa
