This article presents a comprehensive and critical review of the structural performances of reinforced recycled aggregate concrete beams and columns based on experimental results reported in the literature. Extensive data sets collected from the literature are categorized to investigate the effects on the local and global structural behavior. First, the flexural and shear response of reinforced recycled aggregate concrete beams is discussed. The structural performances are reviewed focusing on the main geometric and material variables such as the recycled concrete aggregate replacement ratio, the longitudinal reinforcement ratio, the transverse reinforcement ratio, and the shear span-to-depth ratio. Then, the behavior of reinforced recycled aggregate concrete columns under concentric and eccentric compressive loads and the seismic performance under low cyclic loading are discussed. The similarities and the differences between reinforced recycled aggregate concrete and reinforced natural aggregate concrete beams and columns are highlighted. The need for further research is pointed out at the end of the article. The results reported in this review clearly indicate that reinforced recycled aggregate concrete beams and columns with various recycled concrete aggregate replacement ratios have comparable or slightly lower structural performances to the reinforced natural aggregate concrete ones indicating the feasibility of recycled concrete aggregate for structural applications.

钢筋再生骨料混凝土梁柱结构性能试验结果综述

本文根据文献报道的实验结果，对钢筋再生骨料混凝土梁柱的结构性能进行了全面和批判性的回顾。从文献中收集的大量数据集被分类以研究对局部和全局结构行为的影响。首先，讨论了钢筋再生骨料混凝土梁的弯曲和剪切响应。结构性能的审查侧重于主要几何和材料变量，如再生混凝土骨料替代率、纵向配筋率、横向配筋率和剪跨深度比。然后，讨论了钢筋再生骨料混凝土柱在同心和偏心压缩荷载作用下的性能和低循环荷载作用下的抗震性能。强调了钢筋再生骨料混凝土与钢筋天然骨料混凝土梁柱的异同。文章末尾指出了进一步研究的必要性。本综述报告的结果清楚地表明，具有不同再生混凝土骨料替代率的钢筋再生骨料混凝土梁和柱与钢筋天然骨料混凝土具有相当或略低的结构性能，表明再生混凝土骨料用于结构应用的可行性。强调了钢筋再生骨料混凝土与钢筋天然骨料混凝土梁柱的异同。文章末尾指出了进一步研究的必要性。本综述报告的结果清楚地表明，具有不同再生混凝土骨料替代率的钢筋再生骨料混凝土梁和柱与钢筋天然骨料混凝土具有相当或略低的结构性能，表明再生混凝土骨料用于结构应用的可行性。强调了钢筋再生骨料混凝土与钢筋天然骨料混凝土梁柱的异同。文章末尾指出了进一步研究的必要性。本综述报告的结果清楚地表明，具有不同再生混凝土骨料替代率的钢筋再生骨料混凝土梁和柱与钢筋天然骨料混凝土具有相当或略低的结构性能，表明再生混凝土骨料用于结构应用的可行性。
