In this paper, a numerical study on the effect of normative loads on a thin triangular concrete shell with three supports is presented. Two actions were considered, wind and snow, which present high spatial variability in both intensity and direction, assuming the values established in Eurocode 1 for the worst possible location, in Portugal. Linear, nonlinear and stability analyses were performed using the ABAQUS software. Results suggest that the wind action, but especially the exceptional snow load in drifted arrangement, produce significant bending moments, leading to decompression, and eventually to the development of stresses above the tensile strength of current concrete classes. Therefore, the production of these shells by assembling prefabricated un\u2010reinforced modules, requires the use of ultrahigh\u2010performance fiber reinforced concrete, combined with prestressing.<\/jats:p>","DOI":"10.1002\/suco.202400532","type":"journal-article","created":{"date-parts":[[2024,10,1]],"date-time":"2024-10-01T02:45:37Z","timestamp":1727750737000},"page":"3809-3821","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Numerical investigation on the behavior of thin concrete shells subjected to nonuniform and asymmetrical loads"],"prefix":"10.1002","volume":"26","author":[{"given":"B\u00e1rbara","family":"Cardoso","sequence":"first","affiliation":[{"name":"Civil Eng.
