ABSTRACT: This paper covers some aspects of the bifurcation and elastic geometric non-linear buckling behaviour of hyperbolic paraboloid lattice and concrete shells up to 100 metres in plan size. The paper summaries the important design parameters discovered by earlier research and used variations in the rise to span ratio and edge beam flexural stiffness to undertake a parametric study. The bifurcation buckling of lattices was found to be similar to that of shells. The elastic geometric non-linear analysis was always found to be unstable for shells and stable for rectangular lattices. However, diagonal lattices behaved in a similar fashion to the unstable shells.
