| Abstract: | On the basis of coupling analysis method between geometric non-linear and material non-linear of large span box arch bridge, the method of non-linear finite element analysis towards steel concrete box arch through plane linkage is deduced. Meanwhile calculation program, which is used in non-linear analysis of bridge structure, is made so as to master the force status and damage mechanism of bridge structure. |
