Research On Harmonious Work Of The Roof And The Brace Of The Shell

The question on harmonious work between the roof and the brace of the shell is discussed in the paper. Aimed at the built-up structure between the steel shell and the concrete bracing system,the applied calculating expressions about the damping ratio of the built-up structure made up of the different material is put forward in the paper. Comparing the results which are achieved by calculating the Joint model,the spring model and the whole model of several shells,we will know the result achieved in Joint model way is evidently differenced from its fact. at the same time,the applied calculating method that the spring model replace the whole model is put forward in the paper.The influence imposed on the shell structure by the inertia effect of the nether bracing structure is considered and the earthquake response of the nether bracing structure is also discussed. The advice that the harmonious work between the shell structure and the nether bracing structure should be considered according to the engineer fact.According to structural aseismatic direction, reasonable aseismatic design should allow partial links yield and material go into plasticity. based on theoretic research on the elastic and plastic seismic response of the shell, the example will show the exact analysis of the shell's elastic and plastic performance and the material non-linear influence at the action of the earth is well important.
