Abstract

To improve the structural application of steel fiber-reinforced concrete with recycled aggregates (SFRC-RA) composited in gradation by large-particle natural coarse aggregate and small-particle recycled coarse aggregate, the large eccentric compression behavior of eight SFRC-RA columns was experimentally investigated in this paper. The main parameters considered were the strength of the SFRC-RA and the volume fraction of the steel fiber. Details about the sectional concrete strain, the longitudinal steel bar strain, the lateral displacement, the cracking load, the crack distribution and crack width, and the ultimate load of the SFRC-RA columns were measured. The beneficial effects of steel fiber on these attributes were discussed, and the ductility corresponding to the lateral displacement of the SFRC-RA columns was also analyzed. Based on the test results and design principles, formulas were proposed for predicting the cracking resistance, crack width, and lateral displacement of SFRC-RA columns in a normal service state. The ultimate loads of the SFRC-RA columns under a large eccentric compression load were calculated, considering the second-order effects.

摘要

为改善由大粒径天然粗骨料和小粒径再生粗骨料级配而成的再生骨料钢纤维混凝土（SFRC-RA）的结构应用，本文对8根SFRC-RA柱的大偏心受压性能进行了试验研究。考虑的主要参数为SFRC-RA的强度和钢纤维体积分数。测量了SFRC-RA柱的截面混凝土应变、纵向钢筋应变、侧向位移、开裂荷载、裂缝分布与宽度以及极限荷载。讨论了钢纤维对这些特性的有益影响，并分析了SFRC-RA柱侧向位移对应的延性。基于试验结果和设计原则，提出了预测正常使用状态下SFRC-RA柱抗裂性、裂缝宽度和侧向位移的公式。考虑二阶效应，计算了SFRC-RA柱在大偏心受压荷载作用下的极限荷载。
