Study On Safety Control Of High Formwork Support Considering Human Error

With the continuous development of urbanization in China,the construction industry also continues to progress and development.The high formwork support system is one of the technical means and forms along with the development of the construction industry.In recent years,the application of high formwork support engineering in construction engineering was increasing,and the high formwork support system was constantly developed and improved.However,accidents of high formwork support occured frequently.Summed up the accident of high formwork support,human error is one of the important causes of high formwork support accident.Safety control research on the influence of human error on high formwork support considered as a topic worth exploring.Therefore,the following research work were studied in this paper:(1)Based on the analysis and summary of many high formwork accidents in recent years,we can get that the human errors were one of the main factors influencing the high formwork support safety control,and the mainly human error problems affectting the safety of high formwork support were summarized;(2)Through the study of high formwork support human error,16 selected common human errors were summarized,and the weight of the influence of the fault on the safety of the high formwork support is analyzed with the structure hierarchy system based on human error constructed by analytic hierarchy process;(3)The finite element model considering the influence of human error of high formwork support was established by numerical simulation.The critical buckling load of the high formwork support under the influence of different human error was obtained by buckling analysis method.Through simulation,the main influence of human error on the safety control of high formwork support were analyzed.Compared the results of numerical simulation and analytic hierarchy process,the influence degree of human error on the safety control of high formwork support was studied;(4)According to the above research results,combined with the characteristics of BIM technology,the human error safety control system of high formwork support was constructed based on BIM technology.The points overall safety control system of high formwork support engineering were suggested.
