摘要
通过对5个不同配筋形式、不同荷载分布的墙下六桩承台加载试验研究,验证墙下厚承台的受力性能,揭示墙下厚承台受力符合以混凝土为压杆、承台内钢筋为拉杆的空间桁架模型,承台的破坏源自斜压杆劈裂或拉杆屈服。应用ABQUS软件对承台试件进行弹塑性有限元分析,与试验结果吻合较好。
Experimental research on five large-scaled six-pile caps showed that pile caps under concrete wall conform to spatial truss model with concrete struts and rebar ties.The failure might be caused by splitting of concrete struts or yielding of rebar.Elasto-plastic analysis was carried out with ABQUS program,and the results were highly in accordance with the test results.
