Buckling of Thin Conical Roofs with Edge ring Boundary Conditions
MEng Thesis 2013-14
This website is to make public the research of a Civil Engineering MEng Thesis undertaken by 2 students at the University of Edinburgh in 2013-14.
This research involves modelling various relevant roof geometries under uniform external pressure, and examining structural responses.
It aims to better understand the behaviour of thin shell conical roofs, as commonly found on silos. Results will hopefully contribute to both an improvement of design standards and resulting future design.
Current design standards and recommendations for conical roofs seem unsatisfactory after a little scrutiny. In particular, unrealistic boundary conditions are used, and empirically based recommendations seem to focus on less shallow conical roofs.
The method of inquiry is parametric, computational modelling using the FELASH software suite.
This website is subject to regular updates, and as such you may find blank pages, for example, as of oct. 2013, we have not run any analyses, and so have no results: that section is empty.
