【摘要】 本文基于试验研究,对钢-聚乙烯混杂纤维水泥基复合材料(ECC)与钢筋粘结锚固试件的性能进行ABAQUS有限元分析,并通过试验值与模拟值的对比,验证计算模型的准确性。结果表明,计算分析结果与试验结果吻合较好,所建立的计算模型准确可靠。由试验值及模拟值可知,钢-聚乙烯混杂纤维水泥基复合材料与变形钢筋发生粘结破坏时,ECC试件表现出了明显的延展性。更多还原

【Abstract】 Based on the experimental research,the ABAQUS finite element analysis was carried out on the bond anchorage specimen of steel-polyethylene hybrid fiber cementitious composites with steel rebar in this paper.By comparing the experimental values with the simulated values,the correctness and accuracy of calculation model were verified.The results showed that the calculation and analysis results were in good agreement with the experimental results,and the calculation model was accurate and reliable.It was shown that ECC test specimen has good ductility when the bond failure was occurred between the steel-polythylene hybird fiber cementitious composites and steel rebar.更多还原
