摘要

为分析不同掺量硅粉和聚丙烯纤维对再生混凝土梁抗裂性能的影响，对5根再生混凝土梁的开裂荷载、极限荷载、应力分布和荷载-挠度曲线进行了ANSYS有限元分析。结果表明：硅粉和聚丙烯纤维的掺入，提高了再生混凝土的强度和整体刚度，使得梁抵抗拉应力的能力提高，抗裂性能增强、延性提高，开裂荷载和极限荷载均增大。当硅粉掺量为8%，聚丙烯纤维掺量为0.9 kg/m3时，试件的开裂荷载和极限荷载达到最大值，分别为23.66 kN和128.5kN，较SF₀P₀均提高20%以上。

Abstract:

In order to analyze the influence of different contents of silica powder and polypropylene fiber on the crack resistance of regenerated concrete beams, ANSYS finite element analysis was carried out on the crack load, ultimate load, stress distribution and load-deflection curve of 5 regenerated concrete beams. The results show that the addition of silica powder and polypropylene fiber increases the strength and overall stiffness of the recycled concrete, improves the tensile stress resistance of the beam, enhances the crack resistance, improves ductility, and increases the cracking load and ultimate load. When the content of silica powder was 8% and the content of polypropylene fiber was 0.9kg /m3, the cracking load and ultimate load of the specimen reached the maximum value of 23.66kN and 128.5kN respectively, which were more than 20% higher than that of SF₀P₀.

Key words: silica powder polypropylene fiber recycled concrete beam crack resistance finite element analysis
