This research employs experimental methods to evaluate the performance of large-scale hollow unreinforced 3D-printed masonry walls under axial compressive load. Furthermore, a design methodology tailored for 3D-printed masonry walls under compressive loads is proposed in compliance with both American and Canadian masonry standards. This methodology is supported by the application of linear elastic 3D finite element analysis. Moreover, supplementary insights into material behavior are garnered through the examination of small specimens extracted from an additional 3D-printed wall. The results reveal that 3D printing reduces stiffness and compressive strength. The 3D-printed infills played an important role in redistributing stress after cracking. All full-scale 3D-printed masonry walls examined in this research exceeded the performance criteria set by the American masonry standard for load-bearing walls. <\/jats:p>","DOI":"10.1139\/cjce-2023-0395","type":"journal-article","created":{"date-parts":[[2024,2,21]],"date-time":"2024-02-21T21:40:41Z","timestamp":1708551641000},"page":"919-933","update-policy":"https:\/\/doi.org\/10.1139\/csp-crossmark-policy","source":"Crossref","is-referenced-by-count":15,"title":["Structural performance of large-scale 3D-printed walls subjected to axial compression load"],"prefix":"10.1139","volume":"51","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0586-4444","authenticated-orcid":false,"given":"Marcos V.
