Rizhao One H-beam Countermeasures Research Testing And Strengthening Of The Chongqing Steel Industrial Buildings

Since the reform and opening up,China's industrial development is very rapid,steel plant has been applied to a large area,but over time,the eighties and nineties steel plant life has reached or nearly reached its design life.In order to ensure that these plant structures safe and proper use,these houses often need to carry out structural identification,it must be reinforced for the plant to work properly you must structure structural reinforcement.Especially in recent years,both the steel plant to conduct a comprehensive investigation and security detection,identification and reinforcement,is imperative.This paper reviews and summarizes the characteristics of the steel structure of the plant bent structure,describes the pros and cons of building structures and detection and identification and reinforcement of development,as well as steel reinforcement method of comparison.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,the use of finite element numerical simulation software PKPM a numerical model and computational analysis,modeling some simplified by comparison,cause actual results to detect certain errors.On the bay,crane beams,roof trusses were checking performance analysis.Although the structure of the overall steel plant bent structure is safe,but also found that the individual parts does not meet the regulatory requirements need to be reinforced.By optimizing the actual layout,design,proposed strengthening program structure.
