| Abstract: | In this technical paper,solid and contact elements were employed in ANSYS to create a refined finite element model of pin joints of Dontinghu Bridge to analyze their load and stress conditions.Combining the actual design of pin joints connecting bridge girder and cable,load conditions of joints,contact stress and bearing stress of pin holes of gusset plate were revealed.Furthermore,detailed calculations of nodal zones were performed and their structural capacities were verified using corresponding foreign design guidelines. |
