Fatigue Damage Detection And Identification Of A Steel Structure Factory Building

Today’s society,the rapid development of the national economy,people’s living standards rising,the construction industry has also seen a large number of new structural forms,steel industrial plants,large-span public buildings,steel residential buildings and other steel structure mushroomed.And related to the steel structure materials science,structural design and structural health monitoring work is still in the initial research stage.The actual design and construction there are still many controversies and problems,these problems are an urgent need to address,so as to boost the healthy and rapid development of China’s steel structure.This paper reviews and summarizes the characteristics of the steel frame structure building,the testing technology of the building structure safety and to reinforce the development of technology,and the introduction of steel structure strengthening methods and advantages and disadvantages compared.Second,the theory of the basic principles of dynamic testing of steel are described.Subsequently,through a bent structure steel plant site testing,combined with damage location identification principle to give a review of the calculation parameters of the structure.Finally,using PKPM finite element numerical analysis software modeling analysis.For shelving,the performance analysis and checking calculation of crane beam,truss respectively.Although the structure of the steel frame structure building as a whole is safe,but also found that the individual parts did not meet the requirements of specification need for reinforcement.With practice optimization design,rational structure reinforcement scheme is proposed.
