| Abstract: | Since a self floating elevated trestle bridge has many components, it will be a heavy computation burden if it is directly numerically modeled and calculated. To speed up the calculation, this paper carried out multi condition numerical calculation and analysis by adopting the finite element substructure super element method to study the structural strengths and load bearing capacities of the self floating elevated trestle in various calculation conditions. The results show that the superstructure unit of the self floating elevated trestle can meet the designed requirement of 200 kN vehicle load in the workingcondition; in the surviving condition, the superstructure unit can meet the designed requirement of strength. |
