摘要:
为评价变形不均匀性对钢筋混凝土(RC)柱轴向变形性能的影响,采用MATLAB编制计算程序,对RC柱在单调轴压工况下的荷载变形关系进行计算分析.通过与已有试验结果和有限元方法的对比,验证程序的合理性,并在此基础上进行参数分析.研究表明:是否考虑轴向变形不均匀,对RC柱峰值荷载所对应轴向变形的影响不明显,但是对RC柱极限荷载所对应变形的影响显著,最大差异可超过50%.
Abstract:
The load-deformation relationship of reinforced concrete(RC)columns under monotonic axial load was analyzed by calculation program writing of MATLAB to evaluate effect of axial deformation nonuniformity on the axial deformation performance of RC columns. The program was validated by comparison between existed experimental results and calculation results by FEM method. The parametric study was then carried out. It is indicated that the influence of axial deformation nonuniformity on the axial deformation corresponding to the peak load is not obvious, while the influence on the ultimate axial deformation is remarkable, the maximum difference can be more than 50%.
