The invention discloses a bridge finite
element model modifying method, which comprises the following steps that: 1, an entity finite
element model of a whole bridge is built by universal finite element calculation
software ANSYS; and 2, the entity finite
element model of the whole bridge is subjected to primary modification by a
uniform design method. The bridge finite element model modifying method has the following advantages that the
uniform design method is used as a
test optimization design method with obvious superiority, and the application of the
uniform design method to the bridge structure finite element
model modification is feasible; on the basis of the uniform design method, a more correct result can be found in a very short time by the uniform design method in the efficiency aspect, and the bridge large-scale finite element
model modification efficiency is improved; a response surface method is used as a
test design and mathematical statistics combined mathematical
analysis method, and the application of the response surface method to the finite element
model modification of a large-scale complicated bridge structure is feasible; and higher modification efficiency and higher modification precision can be ensured at the same time.
