The results showed that the creep coefficients in cfrp - confined concrete columns and in epoxy - coated concrete columns are almost same , both are less than that in plain concrete columns on the same other conditions but surface treatment , which demonstrates that the creep reduction in cfrp - confined concrete columns is due to the existence of epoxy coating not of cfrp sheet . furthermore , the physical apperence and dimension have litter effect on the creep behavior of cfrp - confined and epoxy - coated concrete columns 結果表明:其他條件相同時, cfrp約束混凝土柱與涂膠混凝土柱的徐變基本一致,比素混凝土柱徐變小29 . 0 %和26 . 9 % 。 cfrp約束混凝土柱的徐變減小是由于粘貼cfrp布時的膠層所致而非核心混凝土的約束效應。 cfrp約束或表面涂膠的混凝土柱的外形、尺寸及體表比對其徐變的影響很小。
