| Abstract: | According to old L-type signboard structure which may need to be replaced in the reconstruction engineering, a finite element model containing panels,cantilever and pillar is built.The modal of structure is analyzed and natural frequency is obtained.Response on displacement and stress of the structure is calculated under the gravity and wind load.Combined with the technical code,the safety for structure to continue to use is confirmed. |
