CFRP布约束H型钢部分外包混凝土柱的试验与设计方法研究
EXPERIMENTAL STUDY AND DESIGN METHOD OF CARBON FIBER CLOTH CONFINED PEC COLUMN
摘要
Abstract
This paper presents the structure of H-beam partially packed concrete column (PEC column).Based on the axial and eccentric compression tests of 18 PEC column specimens,the effects of different carbon fiber sheet adhesive layers,different carbon fiber cloth paste spacing and different eccentricity on PEC column bearing capacity and failure mode were studied.It was found that the PEC column with carbon fiber cloth was larger than the PEC column with no carbon fiber cloth.Under the same carbon fiber cloth paste spacing,the bearing capacity of the two layers of cloth was larger than that of the single layer of PEC column.The smaller the bonding distance of the carbon fiber cloth,the greater the ultimate bearing capacity of the PEC column.The ultimate bearing capacity of all the test pieces decreases with the increase of eccentricity.Based on the test data,the calculation formula of bearing capacity is put forward.关键词
