Seismic Analysis of a Single-Nave Church Standing on Moderate Sloping Ground: A Church Severely Damaged By the 2009 L’Aquila Earthquake
https://orcid.org/http://orcid.org/0000-0001-5422-8631
The present paper discusses the seismic analysis of a structure standing on moderate sloping ground. The case study is San Giovanni Evangelista church in Casentino, Italy. The façade faces the southwest and slope goes down towards the north and east. It was severely damaged by the 2009 L’Aquila earthquake and is under reconstruction. Collapse mechanisms and damage patterns were considered relevant to sloping ground. In this study, the seismic behaviour of the church is examined with a focus on interaction with the sloping ground. A numerical model was prepared based on in-situ and laboratory tests. The single- and double-flat jack tests of a wall and the chemical analysis of mortar were performed. A three-dimensional spring model and plane interface model were used to discretise contact between the superstructure and sloping ground. Pushover and nonlinear dynamic analysis (NDA) are conducted. NDA considers an accelerogram generated from the L’Aquila earthquake. The paper discusses the seismic behaviour of a church standing on sloping ground and suggests an effective approach to the analysis of such structures.
