通过在已有研究基础上推导出的正截面承载力公式,对比分析一次受力、二次受力下预应力碳纤维布加固矩形混凝土偏压柱正截面承载力的影响因素,分析预应力碳纤维布加固对矩形偏压柱正截面承载力的提高效果,并用ABAQUS有限元分析软件对一次受力、二次受力下普通碳纤维布加固和预应力碳纤维布加固矩形偏压柱的受力全过程进行模拟,对比预应力施加大小、碳纤维布加固层数对矩形混凝土偏压柱力学性能的影响。
Based on the formula of the normal section bearing capacity deduced on the basis of the existing research, the influencing factors of the normal section bearing capacity of rectangular concrete columns under prestressed carbon fiber reinforced plastic Reinforcement of the rectangular cross-section of the columnar bearing capacity of the positive effect, and the use of ABAQUS finite element analysis software, a force, the second force of ordinary CFRP reinforcement and prestressed carbon fiber reinforced rectangular column Simulation and comparison of the impact of the prestressing size and CFRP reinforcement layer on the mechanical properties of rectangular concrete columns.
