Buckling Analysis and Parametric Study of Hemispherical and Pointed Domes with Lamella and Diamatic Configuration

There are different types of domes and different types of failures for the domes. For understanding the behaviour of these dome structures, this thesis was focused on hemispherical and pointed domes with lamella and diamatic configuration. The proposed dome were modelled and analyzed using software ANSYS 16.1 for different rise to span ratios and the results were studied for axial force, maximum moments in the members and deflection of dome and the most effective rise to span ratio for the given span of each type was found. Failure of dome structure is mainly due to buckling of members. Hence a buckling analysis was carried out to find the buckling load of these domes. The behavior of both domes was compared based on the analyzed results and the most efficient shape and configuration among the above was found.
