摘　　要：本文通过ABAQUS有限元分析软件,建立钢筋混凝土L形异形柱的模型,研究肢长肢厚比对CFRP布加固钢筋混凝土L形异形柱力学性能的影响,肢长肢厚比对于不等肢长L形异形柱极限承载力的提高效果明显,且同种肢长比的情况,肢厚数值越大的异形柱,其承载力幅度提高越大.对于肢长比相同的情况下,肢长肢厚比的数值越大,其极限承载力提高幅度越小.可以为CFRP布加固钢筋混凝土异形截面柱在实际工程中的应用提供科学依据和参考.The ABAQUS software of finite element analysis was used to establish a model of reinforced concrete L-shaped special-shapedcolumn to study the influence of limb- to-body thickness ratio on the mechanical propewith CFRP sheets. Extremity limb- to-limb ratio is effective in enhancing the ultimate bearing capacity of L-shaped columns with differ-ent limb lengths. In addition,withthe same limb lengthratio,the larger the limb thickness is,the greater the bearing capacity increa-ses. For the same length and limb length ratio, the greater the value of ratio of the limb length to thickness is , the smaller the increase of the ultimate bearing capacity is. These conclusions can provide a scientific basis and reference for the application of CFRP sheet re-inforced concrete special-shaped section columns in practical engineering.
