This research broadly aims to better understand the nature of thin shell conical roof behaviour.
To relate variable ring area to idealised pinned and roller boundary conditions for a variety of relevant roof geometries.
To obtain predictions of linear bifurcation buckling loads and stress resultants for varying roof geometries under uniform external pressure.
To characterise all analysed relationships such that they may be used in design.
- It is hoped that this research will lead to a better understanding of thin shell conical roof behaviour, such that any suggested improvements to design standards that may result from this research appeal to the reader's inner scepticism and inner Occam's Razor. This will hopefully be achieved by including all necessary variables (notably the addition of realistic boundary conditions.
