基于长宽比变化的FRP加固混凝土轴压矩形柱的试验研究
EXPERIMENTAL STUDY OF FRP-STRENGTHENED RECTANGULAR CONCRETE AS AFFECTED BY ASPECT RATIO
摘要
Abstract
Sixteen concrete columns which is strengthened with FRP sheets were fabricated and studied.The specimens were divided into four groups according to the aspect ratio.One is a control column which is unreinforced,two columns are reinforced by full wrapping with FRP sheet,and one is reinforced by partial wrapping with FRP sheet.The failure mode,bearing capacity and ductility of columns were studied by considering the changes of aspect,the type of the FRP and reinforcement.It was shown that the aspect ratio showed obvious influence on the obtained capability ductility,but had a weak influence on the ductility.The formula recommended by the code for strengthening concrete is verified.According to the test data,a modified model is suggested about the column reinforced by partialwrapping with FRP sheet.关键词
