: The column is one of the most significant structural elements, which is designed to support mainly the compressive load. Strengthening of existing reinforced concrete columns is required to enhance ductility and increase load capacity to sustain the overload as sometimes there may be a change in use. Ten rectangular concrete columns were constructed and tested. H/b ratio was kept constant and equals 6 for all columns The aim of this work is to study the behaviour and efficiency of RC columns strengthened with steel jackets subjected to axial load. An experimental study of the behaviour of ten strengthened concrete columns with slenderness ratio ( 𝐻 / 𝑏 ) equals 6 was carried out. Variables such as aspect ratio ( 𝑡 / 𝑏 ), the volume of steel batten plates, and spacing of steel batten plates at centres ( 𝑆 ) were considered. The results showed that using this method of strengthening is very effective and an increase in the axial load capacity of the strengthened columns is obtained.
柱是最重要的结构构件之一,其设计主要是为了承受压缩荷载。现有的钢筋混凝土柱需要加强,以提高延展性和增加承载能力,以承受过载,有时可能会有使用的变化。建造并测试了10根矩形混凝土柱。本工作的目的是研究钢筋混凝土柱在轴向荷载作用下的性能和效率。对长细比(𝐻/𝑏)为6的10根钢筋混凝土柱进行了性能试验研究。考虑了诸如宽高比(𝑡/𝑏)、钢板条板的体积和中心钢板条板的间距(𝑆)等变量。结果表明,该加固方法有效,加固后柱的轴向承载力得到提高。
