The Study On Analysis Of The Construction Modle And Technology Of Civil Engineering Tests

Based on the structural mechanics capability of the arch bridge, finite element method and similitude theory and summarized the technique and achievement of corresponding bridge structure experiment, we had a research on theory analysis and modeling experiment of the combination of arch and beam. Designed modeling of the combination of arch and beam in found of the similitude theory. Calculated the actual bridge internal forces based on the plane and special finite element program. Making sure the experiment effect, decided the survey points and load styles, comparing the actual stress to calculated results of the controlling section. Created a model to analysis the stress of the changed section of arch rib, the cross section of the beam, and the combination of arch and beam, and concluded the actual responding load of the bridge, under the large-scale finite element analysis program: ANSYS.
