摘要：

In order to study the normal cross-section bearing capacity of steel reinforced recycled concrete columns, 7 specimens were tested under low cyclic reversed loading. The mechanical processes and failure modes were observed, and the bearing capacity of normal cross-section and bending moment-drift angle hysteretic loops were obtained. The influences of the recycled coarse aggregate replacement ratio, axial compression ratio, and stirrup ratio on the normal cross-section bearing capacity were analyzed. Based on the experimental study, an analysis program for normal cross-section bearing capacity was compiled by using a numerical integration method, through which the N-M interaction curve and ultimate strength of steel reinforced recycled concrete columns can be calculated. The theoretical results and experimental results show good agreement. Furthermore, with the program, parametric analysis on N-M interaction curves were carried out, and the laws governing the influence of concrete strength grade, steel strength, steel ratio, and loading angle were obtained. ©, 2015, Tsinghua University.
