| 摘 要： | 针对已有柱子常因各种原因要大幅度增加荷载，而又要求加固后柱子横截面增大不多的问题，本文基于粘钢加固的方法提出了柱子的外包粘钢加固法，同时进行了２７根未加固与外包粘钢加固的短柱的试验研究。研究表明外包粘钢法加固柱子可以大幅度提高柱子承载力，新加固材料与原柱有良好的整体工作性能，而且施工工艺简便，占用空间小，工程费用低，并且加固后的柱子能抗冲撞，有良好的外观等

| Abstract: | Based on the method of strengthening by externally bonded steel plates,the paper proposed a method of strengthening R.C.column by wrapping and bonding steel.This method of strengthening method can solve the problem that the load of the strengthened column needs to be increased significantly but the dimensions of the column cannot be changes obviously.27 R.C.short columns strengthened and unstrengthened are tested.The experimental results show that the load carrying capacity of the strengthened columns is enhanced significantly,and the original R.C.column and strengthening materials can work together well.This technique is simple with negligible changes to the dimensions of the column. |
