Mapping rib-webbing connections in Late Gothic net vaults: A geometry-based typology

Abstract

Nowadays, terrestrial laser scanning of historic buildings provides new geometric data that may supplement or even overwrite the information found in the traditional literature on the topic. This article presents a laser-scanning-based, geometric typology of the connection between the rib system and webbing of Late Gothic net vaults and discusses the underlying building techniques. The article provides not only geometric descriptions but also 12 vaults as case studies to illustrate the different groups and to highlight how the base theoretical outcomes may vary due to the unique building features. After showcasing the typology and the case studies, we discuss the further implications of these results and how they may prove useful for structural analysis or studying the interconnections and genealogy of these buildings.
