| Abstract: | Based on the calculations with ANSYS,it is analyzed how span,rise-span ratio,stiffness of supports and size of grids influence the performance of natural vibrations of single-layer Kiewitt spherical latticed shells.Concluded are the variation rules of natural vibration frequencies and the aseismatic design of positive four-angle conical latticed domes. |
