设置了4个再生保温混凝土剪力墙对照组进行拟静力试验,结合ANSYS有限元分析软件进行再生保温混凝土剪力墙模型建立和分析,研究再生保温混凝土剪力墙的抗震性能。通过对比低周往复荷载下剪力墙构件应力云图和钢筋Mises应力云图,将试验结果与模拟分析相结合,深入研究轴压比、剪跨比、暗柱配筋率及箍筋约束对于剪力墙抗震性能的影响。结果表明:模拟采用的混凝土及钢筋计算模型,其计算值与实验值之间偏差不超过10%,是较为可靠的计算模型;再生保温混凝土比一般混凝土的最大承载力高1.2%~4.7%,因剪跨比不同再生保温混凝土延性系数比普通混凝土高5.1%~12.8%,具有很好的抗震性能;高剪跨比构件拥有更好的抗震性能,且剪跨比对结构的影响程度在加载前期大于加载后期;轴压比从0.14增加至0.3过程中,承载力的提升约为35%,但承载力提升使构件的延性和抗震能力均下降;增加暗柱配筋率能有效提高混凝土构件的延性和抗震能力。

In this paper, four control groups of recycled aggregate thermal insulation concreteshear walls were set up for proposed pseude static tests, and the modeling and analysis of recycledaggregate thermal insulation concrete shear walls were conducted with ANSYS finite elementanalysis software to study the seismic performance of recycled aggregate thermal insulation concreteshear walls. By comparing the stress cloud map of shear wall elements under low circumferentialreciprocal loads and that of reinforcement Mises, the test results were combined with thesimulation analysis to investigate in depth the effects of axial compression ratio, shear-to-span ratio,dark column reinforcement ratio, and stirrup constraint on the seismic performance of shearwalls. The results show that: the concrete and reinforcement calculation model used in the simulation is a more reliable calculation model because the calculated values are in good agreementwith the experimental values and the deviation does not exceed 10%; the maximum bearing capacityof recycled aggregate thermal insulation concrete is 1.2%-4.7% higher than that of normalconcrete, and the ductility coefficient of recycled aggregate thermal insulation concrete is5.1%-12.8% higher than that of normal concrete depending on different shear-span ratios,which has good seismic performance. High shear-to-span ratio members have better seismic performance,and the degree of influence of shear-to-span ratio on the structure is greater in the preloadingperiod than in the post-loading period; the increase of bearing capacity in the process ofaxial compression ratio from 0.14 to 0.3 is about 35%, but the increase of bearing capacitymakes the ductility and seismic capacity of the members decrease; the increase of dark column reinforcementrate makes the members effectively improve the ductility and seismic capacity of theconcrete members.
