Finite Element Analysis of Reinforced Concrete Columns under Small Eccentric Compression Using Cementitious Grout Replacement
摘要
Abstract
A numerical simulation was conducted on 67 reinforced concrete columns,incorporating ce-mentitious grout replacement,under small eccentric compression using ABAQUS finite element software.The study investigated the effects of replacement form,concrete strength,grout strength,and replace-ment rate on the bearing capacity of these columns.The results indicated that as the cementitious grout strength and replacement rate increased,the bearing capacity of the reinforced column also increased.However,as concrete strength increased,the rate of bearing capacity improvement gradually diminished,with a maximum increase of 13.6%.When the replacement thickness was held constant,applying four-side replacement reinforcement allowed the reinforcement material to provide additional constraints,and restricted the initiation and development of cracks,thereby enhancing the column's bearing capacity.Ad-ditionally,when the replacement rate was constant,using the opposite-side replacement reinforcement method effectively increased the local stiffness of the column,resulting in a more uniform force distribu-tion and improving its load-carrying capacity.关键词
