摘　　要：再生混凝土技术通过对废弃混凝土的再加工,使其恢复原有的性能,通过合理的配合比设计,形成新的建材产品,从而既能使废弃的资源得以再利用,又在一定程度上解决了环保问题,这是发展绿色混凝土,实现建筑资源环境可持续发展的有效措施之一。在介绍再生混凝土的发展及钢管再生混凝土轴压短柱、纯弯构件和压弯构件初步研究成果的基础上,对钢管再生混凝土力学性能和设计方法的若干问题进行探讨。The technology of recycled concrete restores the original performance of waste concrete by re-processing of the waste concrete and forms new building material through reasonable design of mix proportions, thus reuses the waste resource and solves the problem of environment protection. This technology is one of effective steps to develop green concrete and can achieve sustainable development of building, resource and environment. It is briefly introduced the developments of the recycled concrete and the preliminary achievements of axially loaded stub columns, beams and beam-columns are presented generally. Finally, the need for further research on mechanical behavior and design method of recycled conerete-filled steel tubular members is discussed.
