| Summary: | From the perspective of engineering practice,analysis of stiffened composite wall slab with a Delaminatong at the stringer interface in this paper,and typical structure / typical Delaminatong type is simulated using finite element method. In view of reasons of Delaminatong,feasible proposals of damage control and repair have been raised. Full-scale static test of structures with Delaminatong has indicated that the integer load-carrying capability is determined by the stability of the wall slab. Going with the increase of the working stress due to the Delaminatong between the stringer and the skin,local sustain stiffness of the skin is reduced,resulting in descending of initial bucking load and integer capability of load-carrying. Correctness of the finite element analysis method has been preferably verified by the results of test. |
