Abstract: The building cover of the proposed stadlium adopts the honeycomb lU-shaped steel-concrete combination honeycomb fastingsandwich plate with a span of 39.26m, and the dynamic characteristics of the building cover are modleled and analyzed. The results showthat the U-shaped steel-mixed honeycomb type fasting plate building cover has good inlegrity, and the rigidity distribution of the buildingcover is uniform.The fundamental frequency value of the building cover meets the requirements of domestic norms. The inluence of upperand lower rib beams on the fundamental frequency was analyzedl, and the results showed that the increase of the height of the lower ribbeam was more effective for improving the rigidity of the roof.
Key words: honeycomb fasting sandwich plates; modality; dynamic characteristics; fundamental frequency; rib beam
