ansys连续梁桥(ansys连续梁桥)
The key steps of modeling and analysis are as follows:
The center line 1, box beam to simulate the plate thickness is the sideline, box girder floor, roof, web and flange plate.
2, determine the location of each key point.
The thickness of flange and floor 3, correct simulation of chamfering and the thickness of the gradient.
4. After entering into the process, analyze the stress and deformation.
