摘要
应用数值分析软件对一三层板柱混凝土结构的施工全过程进行了模拟分析,并将模拟结果与1∶1的实际试验[1]结果相对比,验证了数值分析的可靠性。以此为基础进行的进一步研究发现,模拟值与试验值的变化趋势是一致的,其绝对值也比较接近,但模拟值要小于实际值;此外,模拟分析也证实,在施工期间,施工荷载不断在支撑和楼板之间发生重分配,随着楼板混凝土强度的增加,楼板分担的荷载越来越大,支撑分担的荷载越来越小。
This paper modeled the overall process of construction of a simple three-level concrete structure with numerical analysis software.Comparison between the results of simulation and experiment verified the reliability of numerical analysis.The research shows that experimental value and modeled value varied with the same variation trend and the absolute values of them are closed.However,the modeled value is less than experimental value.Besides it,construction load keeps redistributing during construction.With the increasing of concrete strength,loads shared by floors are increasing,while those shared by shores are decreasing.
