Research On Structural Stress Analysis And Reinforcement Of Gate Shaft Based On BIM And ANSYS

"BIM+" has been widely used in the fields of Internet,architecture and geographical environment due to its great advantages in combination with other technologies,but its application in the field of hydraulic structure is still in primary stage.Therefore,I based on the current research on the construction,structure,reinforcement and other aspects of the gate shaft and based on BIM+finite element analysis,puts forward the idea of BIM intelligent model creation,and analyzes the influence of reinforcement parameters on shaft strength in combination with ANSYS,so as to improve the research direction and content of the gate shaft.The main contents and results are as follows:(1)Taking BIM technology as the platform,I completed the intelligent creation of the gate shaft model through the secondary development of Revit.(2)Taking the gate shaft as the research object,I analyzed the stress of each component of the gate shaft.The results show that the maximum stress of the wellbore is located in the contact part of the wellbore and the well seat,the maximum stress of the well seat occurs at the gate hole,and the maximum stress of the transition section appears at the edge of the outermost layer on the upper part of the round end section.(3)I studied the influence of steel bar spacing and steel bar diameter on the overall deformation strength of the wellbore.The results show that,under the premise of meeting both the minimum reinforcement ratio and the reinforcement specification,when the steel bar diameter is constant,choosing a small steel bar spacing has less impact on the overall deformation of the wellbore;when the steel bar spacing is constant,choosing a big steel bar spacing has little effect on the overall deformation of the wellbore.
