L’Aquila w s a highly rewarding experience of scientific growth and personal maturation. Yet, it was also quite a demanding time because of my wife, professor at the Academy of Fine Arts of Naples, and my two kids living in Rome. Probably, fore ign colleagues accustomed to a great permeability between different universities and hosting cities will be a mazed by this observation. But, the Italian social, cultura , and academic environment has always been characterized by a strong sense of local identity, in particular when the original place of scientific activity was a prestigious u niversity (a perception which, luckily, has almost entirel y vanished in recent decades). At the branch of the Department of Structural and Geotechnic al Engineering of the School of Architecture of Rome, I found Patrizia Trovalusci, a fine and highly motivate d young researcher (a tenured position equivalent to an assistant professor) whom I had already met at a couple of con ferences, and who had received her PhD degree three years before. Being quite inexperienced of the peculiar env iro ment of a school of architecture, I did my best for not moving there like an elephant in a crystal shop, and I subs tantially succeeded in this. In particular, I paid strong attention in not exerting the academic power of a new profess r, appointed to establish a quality team in solid and structural mechanics, for bringing the richness, but also t he “weight” and complexity, of my scientific background in nonlinear dynamics of structures and mechanical systems into an environment substantially unaware of them and instead promisingly active in a different field. This was esp ecially true as regards my “assistant” Patrizia, who was just coauthoring some interesting papers on continuum mode ls f masonry, along with an older colleague. In the few years to come, I took some nontrivial effort to properly gras p how much potential was indeed embedded in the more general research program on micropolar and classical conti nua for anisotropic discontinuous materials, which Patriz i was progressively and fruitfully working on. And indeed, ca tching the importance of promoting and supporting an unprecedented, even if quantitatively minimal, quality gr oup also in a different area of research, I maintained the poi nt of not reorienting Patrizia’s scientific activity towards t he completely new area of nonlinear and chaotic dynamics, leaving her full freedom of choice and responsibility in thi s respect. As a matter of fact, this was (and still is) my conceptual position about the correct way to foster the adva ncement of research in whatever scientific environment. I made such a choice despite the high qualities of Patrizia ","PeriodicalId":50350,"journal":{"name":"International Journal for Multiscale Computational Engineering","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67460931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

J. Solids Struct., vol. 2, no. 2, pp. 249-279, 1966) and on the safe theorem of the limit analysis (LA), an in-depth numerical study of a case study based on a masonry spiral staircase in Nisida, near Naples, is here presented by means of an accurate finite element (FE) model. The nonlinear FE model has been obtained by the use of the ANSYS Parametric Design Language (APDL), and a precise representation of all the material involved and of the boundary conditions, has been obtained. The results confirm that LASA can be an alternative to much more complex numerical analyses, such as FE, but it cannot account for the main cause of collapse or stress redistribution in these type of structures, that is sagging and subsidences. The results are presented and discussed in some detail.","PeriodicalId":50350,"journal":{"name":"International Journal for Multiscale Computational Engineering","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138513214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
