REVIEW ON THE EFFECTIVE ULTIMATE TENSILE STRAIN OF FRP FOR FRP-CONFINED CONCRETE COLUMNS UNDER VARIOUS FACTORS
摘要
Abstract
FRP confinement effects make concrete columns under the statement of triaxial compression,which improves the compressive strength and ductility of concrete columns.Effective ultimate tensile strain of FRP is essential for calculating the lateral restraint force,proposing peak stress models,peak strain models and stress-strain models of confined columns.In addition,the influence parameters are various.Researchers have obtained some meaningful but discrete and limited results on the effective ultimate tensile strain of FRP.In this paper,systematic analysis was conducted on various influence parameters based on the existing research results,and the remaining problems and key issues which need to be focused in future are pointed out.关键词
