PVC-FRP管钢筋混凝土柱轴压比限值研究
STUDY ON LIMIT AXIAL-LOAD RATIO OF PVC-FRP CONFINED REINFORCED CONCRETE COLUMN
摘要
Abstract
The mechanical behavior is analyzed according to the stress-strain relationship of PVC-FRP confined reinforced concrete column.Based on the equilibrium condition of large and small eccentric limit compression,the basic assumptions for limit axial-load ratio of PVC-FRP confined reinforced concrete column are proposed,and then a calculating method of limit axial-load ratio is derived.It is shown that the limit axial-load ratio of PVC-FRP confined reinforced concrete column decreases with the increasing hoop spacing of CFRP strips.The limit axial-load ratio of PVC-FRP confined reinforced concrete column is gready improved compared with that of reinforced concrete column.关键词
