Abstract: Subspace iteration method was used to analyze the self vibration characteristics of three-dimensional grids monolayer elliptical paraboloid shell, the influence to self vibration characteristics was studied too. Then mode analysis method was used to calculate the seismic response of the shell structure on different direction earthquake, On the basis of result analysis, some useful conclusion was put forward and some theory foundation was provided for engineering application of three-dimensional grids monolayer elliptical paraboloid shell.
Keywords: monolayer ellipse paraboloid shell; three-dimensional grids; self vibration characteristics; seismic response
