| Abstract: |
| In this paper, the dynamic problems of globular lattice flat shells were studied and the general vibration equations were derived by using the method of simulated shell. In the case of simply supported lattice flat shells * the solution of vibration equations would easily be calculated by using two functions of a double trigonometric series. When vertical earthquske wave applied on the shell, the solution would be given similarly. The coefficient in the formulas is very close with the standard GBJ11-89 and can be obtained by using the vertical seismic response spectrum method. |
