Finite element thrust line analysis of axisymmetric masonry domes

International Journal of Masonry Research and Innovation (IJMRI), Vol. 1, No. 1, 2016

Abstract: A new method for analysis of axisymmetric masonry domes is proposed here combining the simplicity of the thrust line with the versatility of the finite element approach, where a modified axisymmetric element incorporates the hoop tension effects. This method is able to obtain the thrust line of an axisymmetric masonry dome more accurately than the existing graphical approaches. The case study on a hemispherical axisymmetric dome shows the effectiveness of the proposed method. The results reaffirm the notions of classical thrust line analysis and postulates on the minimum thickness of a stable dome.
