The masonry buttressed arch on spreading support

Abstract This paper analyses the ultimate states of a circular masonry arch supported on rectangular slender abutments when subjected to an imposed settlement of one support in addition to self weight using the principle of virtual work and thrust line analysis Depending on the angle of settlement and the slenderness of the arch and the abutments the study identifies the main hinging

The masonry arch on spreading supportsThe Institution

This paper seeks to determine the horizontal support movements necessary to cause collapse for a rigid block arch For masonry arches in historical buildings small movements of the supports can destabilise the arch and can lead to collapse over time As the supports move apart the geometry of the arch adapts causing the crown of the arch to descend which increases the value of horizontal
