Force Analysis of Steel-Concrete Composite Beam Stud Connectors in Cross-Sea Cable-Stayed Bridges
Stud shear connectors are crucial for enabling the collaborative functioning of concrete bridge panels and steel box girders.This research utilized ANSYS finite element software to conduct a practical test,aiming to vali-date the simulation method's effectiveness and accuracy through analyzing its shear capacity with precise modeling.Subsequently,this method was employed to simulate the shear resistance of the stud shear connector in practical en-gineering.The failure mode and shear performance were then examined by using stress cloud mapping and load-slip curve analysis.Ultimately,the simulation values of a single bolt were compared with the standards and empiri-cal formulas utilized in different countries.The results indicate that the test values of the four groups are marginally greater than the calculated values of the finite element simulation,with a margin of error of less than 10%.This suggests that the finite element analysis approach is reliable and suitable for practical engineering applications.When the stud shear connection suffers shear,the stress focuses on the base of the stud,which causes deformation in the concrete.However,it is capable of withstanding larger ultimate loads,and there is minimal slippage between the concrete and the steel plate.The simulated calculated values closely align with the specifications of our coun-try,and the design adheres to the established technical principles.The results can serve as a point of reference for similar engineering designs.
