The Stability Of Slender Masonry Millions
Author(s)
A.R. Selby
Abstract
During the building of the great cathedrals of Europe, masons endeavoured to
produce larger windows with more slender mullions, so as to flood the building
with natural light. These were later glazed with stained glass, giving rich colours
to the interiors. There is limited anecdotal reference to window collapse;
however, one of the larger windows in Durham Cathedral has an internal masonry
frame which appears to have been constructed to provide added resistance of the
window to inward collapse under severe wind loading. This curious architectural
detail is the reason for this study into window stability. Two windows in Durham
Cathedral have been studied to consider their factors of safety against mullion
instability.
1. Introduction
Since Mediaeval times, masons and architects have extended their skills and
experience into larger windows, with taller and more slender masonry mullions.
