Abstract

The single-layer spherical reticulated shell is the structure which is sensitive to imperfections. The initial imperfections reducing structural stability included initial curvature and residual stress of element and installation deviation of nodes. The stress-strain curve concerning the residual stress was got by model CRC, the influence of initial curvature was got by the half-sinusoid and the programs about them were programmed by ANSYS secondary exploitation. Based on these works, the influences of the three imperfections on dynamic failure of the spherical reticulated shell were got by IDA.
