摘 要:通过ANSYS软件模拟了单调加载作用下不同再生骨料取代率再生混凝土柱的受压性能,得出了荷载-侧向位移关系曲线和荷载-混凝土应变关系曲线,并与相应的试验结果进行了比较分析。结果表明:有限元分析得到的破坏形态、混凝土应变及侧向位移与试验结果十分接近,验证了ANSYS分析再生混凝土受力性能的有效性。
Abstract: The load-strain curves of concrete and the load-displacement curves are carried out by ANSYS software simulating the loading capacity of recycled aggregate concrete columns with different percentage replacement of recycled coarse aggregate under monotonic loading, and the analysis results are compared with the experimental results. The results show that the failure mode, the concrete strain and the lateral displacement obtained by finite element analysis are close to the experimental results, which can verify the validity of ANSYS software to analyze the loading capacity of recycled aggregate concrete.
