Analysis On Technical Problems Of Jilin Fitnessc Enter

The construction project development situation at home and abroad shows that when the structure technology development to a certain stage, both the reinforcement and the repair of existing structure will be our main building tasks. Nowadays, because of the superficiality of the reinforcement design, the low quality of construction and that the re-inforcement designer are partly non-professional, the reinforcement and the repair project are suffering from many problems, which are hindering the renovation and the develop-ment of the reinforcement and the repair technology in our country.This paper takes National Fitness Center in Ji Lin as research object. The response analysis on the whole structure has been carried out through MIDAS. And the response is gained, according to which the strengthening scheme is proposed and the durability of the structure is improved. This paper is mainly divided into four parts:1.Choose double layers dome shell as the upper roof of the structure and build up the calculation model of the whole structure. The analysis works contain static analysis, time history analysis and buckling analysis. The results show that the whole performance of the structure is good.2.Referring to the technology of the connection between the old and new concrete, make the junctional zone rough, then add interfacial agent to the surface and increase the reinforcement at the node place to improve the shear strength.3.The results show that the carrying capacity of some frame beams can not meet the design requirements. Based on the results, the carrying capacity of concrete structure is strengthened by using the reinforcement method of augmented section or steel plate pasting.4.Cracks grow at the beams and plates, steel corrosion occurs in the concrete and the concrete surface of the stand becomes weaker. To solve these problems, the durability of the structure is repaired.
