- Abstract:
- The spatial finite element calculation model of the 120 m span reclining arch bridge of the main bridge of Chengdonghe Zhanhe Bridge in Pingdingshan City was established by using Midas/civil finite element software, and the static characteristics of the bridge under constant load and constant load + live load were calculated. The calculation results show that the concrete components of the whole bridge are generally in a compression state, the maximum positive stress value of the rod beam is 6.28 MPa, and the maximum positive stress value of the arch rib is 12.0 MPa, both of which are less than the C50 concrete design compressive strength: the safety factor of the main arch boom is 2.94, the safety factor of the stable arch boom is 2.70, and the minimum safety factor that meets the design requirements of the arch bridge shall not be less than 2.5: the maximum vertical displacement of the tie beam is 0.039 m, and the maximum vertical displacement of the arch rib is 0.03 m. The maximum lateral displacement is 0.101 m, which meets the deformation requirements under the normal service limit state of the bridge design code.
