The current research on alkali-aggregate mainly focuses on the deterioration mechanism of materials and the mechanical properties of standard specimens. However, there is a gap in the field of research on the effect of alkali-aggregate damage on the level of RC structures. In this study, five RC beams were tested, and the depth and location of alkali solution immersion were used as the test variables, with the aim of investigating how the steel reinforcement suppresses the expansion caused by ASR and evaluating the shear behavior of RC beams after non-uniform ASR damage. The results of the study showed that immersion in an alkali solution and an increase in immersion depth accelerated the rate of expansion development, while steel reinforcement inhibited the rate of expansion development. Compared with undamaged RC beams, ASR initially generates expansion stresses within the concrete, which increase the cracking and yield loads of RC beams and delay the cracking of RC beams, and ASR reduces the ultimate load-carrying capacity and ductility of RC beams due to the disruption of the concrete microstructure. Finally, a chemo-mechanical analysis method is proposed based on experimental results, which incorporate an ASR expansion model and a pore mechanics model. The efficacy and precision of this model are validated through comparison with experimental results.<\/jats:p>","DOI":"10.3390\/ma18020312","type":"journal-article","created":{"date-parts":[[2025,1,13]],"date-time":"2025-01-13T05:40:40Z","timestamp":1736746840000},"page":"312","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Expansion Characteristics and Shear Behavior of Reinforced Concrete Beams Under Non-Uniform Expansion Induced by Alkali\u2013Silica Reaction"],"prefix":"10.3390","volume":"18","author":[{"given":"Feng","family":"Sheng","sequence":"first","affiliation":[{"name":"State Key Laboratory of Hydroscience and Engineering, Tsinghua University, Beijing 100084, China"},{"name":"PowerChina Roadbridge Group Co., Ltd., Beijing 100048, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuehui","family":"An","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Hydroscience and Engineering, Tsinghua University, Beijing 100084, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mengliang","family":"Li","sequence":"additional","affiliation":[{"name":"PowerChina Roadbridge Group Co., Ltd., Beijing 100048, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuxiang","family":"Zhou","sequence":"additional","affiliation":[{"name":"PowerChina Roadbridge Group Co., Ltd., Beijing 100048, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pengfei","family":"Li","sequence":"additional","affiliation":[{"name":"Engineering Research Centre of Diagnosis Technology of Hydro-Construction, Chongqing Jiaotong University, Chongqing 400074, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,11]]},"reference":[{"key":"ref_1","first-page":"65","article-title":"Stiffness degradation of concrete due to alkali-silica reaction: A computational homogenization approach","volume":"117","author":"Nguyen","year":"2020","journal-title":"ACI Mater.
