| Abstract: | Xipan highway Anning River bridge and its main span box girder makes use of the strut-beam construction, its steel bracket uses military girder.The size of each cage of steel bracket is 46.96 meters long, 3.28 meters wide, 4.69 meters high, and 730KN in weight.To complete the installation and unloading of steel bracket of such great weight smoothly involves complex structure stress and many difficulties in swing.By way of analyzing the structures and processes in the installation or unloading of the steel bracket, also by using the finite element computation software Algor 16 pair of structure modeling analysis integrated with previous construction experience, we smoothly completed the installation and unloading of steel brackets. |
