Stability and rocking response of non-uniform masonry arches: The ‘part-elliptical’ profile
Highlights A part-elliptical arch uplifts for higher acceleration levels than a circular one. Under idealised pulses, part-elliptical arches are more stable than the circular ones. The dynamic response is well captured with both analytical and finite element methods. The part-elliptical arch geometry highly affects stability and rocking response.
Abstract The fundamental role of geometry on the stability of historical arched structures has been unveiled centuries ago. In this study, a segmental arch consisting of an elliptical upper part (extrados) and a circular lower part (intrados) is introduced. This so-called part-elliptical arch is treated as a rigid monolithic body enabled to rock on a triggering base. The objective of the study is to extend the established methods applicable to the conventional circular arches, particularly in terms of: (i) stability analysis at incipient uplift, (ii) time-history analysis of the rocking response. The results are presented comparatively to those extracted from the circular arch of the same geometric characteristics.
