摘　　要：对1根普通混凝土柱和3根再生混凝土柱模型进行低周反复荷载试验研究。再生混凝土柱分别为普通再生混凝土柱、含再生砖粒再生混凝土柱及硅粉和纤维增强的再生砖粒混凝土柱。通过试验对比分析了4根柱子的破坏形态、滞回特性、刚度退化、延性性能、能量耗散及其承载力,从而进行砖粒及硅粉和纤维增强的砖粒再生混凝土柱抗震性能的研究。研究表明:相对于普通混凝土柱,3根再生混凝土柱的抗震能力呈下降趋势。但是,掺入再生砖粒的再生混凝土的弹性模量和延性都明显下降,而硅粉和纤维的掺入可明显提高其弹性模量和延性性能。Low-cycle loading tests were carried out for 1 common concrete column and 3 recycled concrete columns models. Recycled concrete columns were respectively ordinary regeneration concrete column, regenerated brick granules recycled concrete column, silicon powder and fiber reinforced regenerated brick granule recycled concrete column. Through the experiment comparison, it was analysed the failure modes, the hysteretie performance, degradation of rigidity, ductility, energy dissipation and the load capability of the 4 specimens. Based on which it was studied the seismic performance of the brick granules and silicon powder and fiber reinforced recycled concrete column. Research showed that compared with ordinary concrete column, the seismic resistance of 3 pieces of the regenerated concrete columns was decreased. But regenerated brick grains recycled concrete elastic modulus and ductility were significantly decreased, and silicon powder and fiber could obviously improve their elastic modulus and ductility performance.
