{"title":"A Comparison Between Empirical Procedures for the Definition of Vulnerability Classes of Masonry Buildings: Application to Five Historical Centres Struck by 2016 Central Italy Earthquake","authors":"Y. Saretta, L. Sbrogiò, M. Valluzzi","doi":"10.23967/sahc.2021.003","DOIUrl":"https://doi.org/10.23967/sahc.2021.003","url":null,"abstract":". The definition of seismic risk scenarios necessarily depends on the attribution of a vulnerability class to each building of a stock. In the macroseismic scale (EMS-98) the vulnerability class – from A to F – results from the combination between horizontal and vertical structures. On the basis of post-event surveys carried out in Italy after the earthquakes occurred in the last 50 years, many rules for converting the masonry quality and the stiffness of horizontal diaphragms into a vulnerability class have been proposed. However, despite the now high number of retrofitted or strengthened buildings in Italy, structural interventions are not mentioned in these procedures, except for metal tie rods and r.c. tie beams. The paper proposes a critical approach to the definition of vulnerability classes, by the means of applying the conversion rules to the same sample of 525 masonry buildings located in five historical centres struck by 2016 Central Italy earthquake: Acquasanta Terme, Campi Alto di Norcia, Castelsantangelo sul Nera, Muccia and Vezzano. They have been chosen due to the extensive strengthening campaigns that had been carried out after earlier seismic events. The preliminary recognition of the structural features of each building happens at the terms of the MUSE-DV Masonry, a rapid visual screening procedure recently proposed by the authors. The damage probability matrices (DPMs), obtained from each conversion, are compared to those from a theoretical model proposed for the EMS-98. Given the same poor masonry quality, the existing rules","PeriodicalId":176260,"journal":{"name":"12th International Conference on Structural Analysis of Historical Constructions","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130507419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Typological Classification and Observed Damage Patterns of Masonry Churches After the 2016 Central Italy Earthquake","authors":"G. Cianchino, C. De Matteis, G. Brando","doi":"10.23967/sahc.2021.311","DOIUrl":"https://doi.org/10.23967/sahc.2021.311","url":null,"abstract":". The seismic protection of cultural heritage is an important topic that has been faced by several researchers in the last decades. Seismic events of the past have highlighted the need of achieving a proper knowledge of the vulnerability of cultural heritage, in particular of churches, in order to put in the field proper mitigation measures at the large scale. According to this premise, this paper deals with the damage scenario observed on eighty seven churches hit by the 2016 Central Italy earthquake. In a first stage, the most important structural features of the studied churches are discussed and threated by the statistical standpoint. The reported information have been collected through the A-DC form, adopted by the Civil Protection Department and by the Ministry of Heritage and Cultural Activity and Tourism (MiBACT), which was used in the framing of the damage reconnaissance activity carried out by the ReLUIS Italian consortium in the aftermath of the earthquake. Also, the form has been used in order assess the damage of each macro-element and, then, to assign a damage index to each church. The presented work is framed in a wider research activity that aims at providing a predictive methodology for the vulnerability assessment of churches at the regional scale. This methodology was already calibrated on the basis of the 2009 L’Aquila seismic event. The outcomes presented in this paper will serve to further prove the reliability of the proposed model.","PeriodicalId":176260,"journal":{"name":"12th International Conference on Structural Analysis of Historical Constructions","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130675270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since 2014, the Delft University of Technology started a research program to assess the seismic response of unreinforced masonry (URM) buildings. The Dutch URM buildings are characterized by slender piers and transverse walls. In common practice, the connections between piers and transverse walls are often modelled as rigid, but in real structures these connections may exhibit different behaviour. Especially, since the 1980s, calcium silicate element masonry has been commonly used in Dutch buildings, and vertical continuous joints are present between transverse walls. For this reason, it appears essential to assess the connection strength properties, since its failure can significantly reduce the seismic performance of the entire structure. The first part of this work investigates and compares different numerical approaches to describe the nonlinear behaviour of masonry under lateral loads, simulating seismic action. The second part specifically focuses on the critical issues related to the modelling of vertical connections of Dutch URM buildings. A sensitivity study of the frictional parameters is performed to analyze the influence of the strength of the glued connection on the global response of the URM structure.","PeriodicalId":176260,"journal":{"name":"12th International Conference on Structural Analysis of Historical Constructions","volume":"229 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132019130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zuppiroli","doi":"10.23967/sahc.2021.283","DOIUrl":"https://doi.org/10.23967/sahc.2021.283","url":null,"abstract":"Seven years after the earthquake occurred in Emilia-Romagna, the planning phases related to the cultural heritage reconstruction are coming to a conclusion. At this point, the Agency for reconstruction earthquake 2012 has launched an unprecedented process aimed at verifying, also through the recognition of the main critical issues, the simplified damage assessment procedures whose application has allowed an aware and sustainable management of the emergency. These procedures able to become practices in the ordinary management of the territory. The Guidelines for the evaluation and reduction of seismic risk on Cultural Heritage, and the Directive 12/12/2013 “Procedures for management of activities for cultural heritage securing and safeguarding in the event of emergencies caused by natural disasters” of MiBAC identify as first cognitive procedure the compilation of sheet to provide vulnerabilities and damage level representation on movable and immovable assets. In particular, they establish two important survey instruments: the A-Church and the B-Palaces sheets. These are the only two instruments used between 2012 and 2013 for the damage level characterization of the cultural heritage caused by the “Emilia 2012” earthquake. The widespread use of these sheets has brought to light several problems that have negatively affected the successive economic assessment of the intervention. In fact, if these sheets well describe the vulnerabilities of the specialized types Churches or Palaces, they are ill suited to types with different features, which, in the Emilia-Romagna case, represent about 30% of damage cultural heritage numerically and economically. In particular, concerning cemeteries, which constitute the most relevant sample in this set, the operator's difficulty in choosing the sheet type to use, A or B, has been underlined. Furthermore, the B model modification, lately introduced by MiBAC to simplify the procedure, has further aggravated the situation with the illogical consequence of having 7-8 sheets per single cemetery, regardless of its size. After the analysis of all sheets produced for the cemetery type after the 2012 earthquake, the need to implementation for the already consolidated procedures has become clear, in order to be able to manage the post-emergency phases on those types that, as cemeteries, represent an important part of the local cultural identity, but that are not addressed in existing tools.","PeriodicalId":176260,"journal":{"name":"12th International Conference on Structural Analysis of Historical Constructions","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133161227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to study the architectural form and the structural performance of this special type of architectural heritage, the brick-vault hall of Yongzuo Temple was taken as an example to study. The accurate geometrics dimension of this building was first obtained by the survey of three dimensional laser scanner. Then, with the comparative analysis of some relevant historical literatures, the architectural form of this building was studied. Furthermore, the material strength was achieved with the non-destructive testing method, the finite element model of this building was built up to analyze its structural performance based on the accurate geometric dimension and the accurate material strength.
