Its effects can harm structural elements by reducing mechanical capacity, mainly due to diminished reinforcement properties and expansive reactions within the concrete. In addition, the effects of punching shear on flat slabs can be detrimental, as failure of the slab\u2010column connection can trigger a progressive collapse of the entire structure. This study focused on investigating three reinforced concrete flat slabs, based on experimental results concerning punching shear capacity when subject to reinforcement corrosion. The slabs, without shear reinforcement and including openings adjacent to the slab\u2010column connection, were subjected to a corrosion degree of 20%. Finite element models were developed using ABAQUS software. Modeling methods were applied to analyze the effects of corrosion on the geometric and mechanical properties of reinforcement, concrete, and steel\u2010concrete adhesion. The results showed that, as corrosion increased, the ultimate load of the slabs decreased. Specifically, there was an average reduction of 23.4% for 20% corrosion. The stiffness and ductility of the slabs were affected, especially those with openings adjacent to the column. Following load\u2013displacement analyses of the slabs, the punching load capacity results were compared to the estimates from Eurocode 2, NBR 6118, ACI 318,\n                    <jats:italic>fib<\/jats:italic>\n                    Model Code, and FprEN 1992 1\u20101 codes. The normative codes underestimated the strength capacity of corroded slabs, proving conservative, with Eurocode 2, NBR 6118, and FprEN 1992 1\u20101 providing the most precise and least dispersed results.\n                  <\/jats:p>","DOI":"10.1002\/suco.70441","type":"journal-article","created":{"date-parts":[[2025,12,20]],"date-time":"2025-12-20T02:04:10Z","timestamp":1766196250000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Numerical analysis of the effects of corrosion on the punching shear capacity of reinforced concrete flat slabs with openings"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-5560-0237","authenticated-orcid":false,"given":"Vin\u00edcius D'Almeida Rodrigues","family":"Ramos","sequence":"first","affiliation":[{"name":"Civil Engineering Department State University of Maring\u00e1  Maring\u00e1 Paran\u00e1 Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4631-9290","authenticated-orcid":false,"given":"Leandro Mouta","family":"Trautwein","sequence":"additional","affiliation":[{"name":"School of Civil Engineering University of Campinas  Campinas S\u00e3o Paulo Brazil"}]},{"given":"Ant\u00f3nio Pinho","family":"Ramos","sequence":"additional","affiliation":[{"name":"CERIS, Civil Engineering Department NOVA School of Science and Technology  Caparica Portugal"}]},{"given":"Elyson Andrew Pozo","family":"Liberati","sequence":"additional","affiliation":[{"name":"Civil Engineering Department State University of Maring\u00e1  Maring\u00e1 Paran\u00e1 Brazil"}]}],"member":"311","published-online":{"date-parts":[[2025,12,19]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.engstruct.2018.11.073"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.14359\/13390"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/suco.201700201"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.istruc.2020.05.004"},{"key":"e_1_2_11_6_1","volume-title":"Eurocode 2: design of concrete structures \u2013 part 1\u20131: general rules and rules for buildings","author":"EN","year":"2004"},{"key":"e_1_2_11_7_1","volume-title":"ABNT NBR 6118 \u2013 design of concrete structures \u2013 procedures","author":"Brazilian Association of Technical Standards","year":"2023"},{"key":"e_1_2_11_8_1","volume-title":"ACI 318R\u201019: building code requirements for structural concrete and commentary","author":"American Concrete Institute","year":"2019"},{"key":"e_1_2_11_9_1","volume-title":"Fib model code for concrete structures 2010 (MC 2010)","author":"F\u00e9d\u00e9ration Internationale du B\u00e9ton (fib)","year":"2020"},{"key":"e_1_2_11_10_1","volume-title":"1992\u20101\u20101.
