混凝土框架柱的加固试验研究

本文对１２根混凝土框架柱试件采用三种方法进行了加固，并对这三种方法加固的试件进行了静载试验，获得了加固柱的新，旧混凝土共同工作的规律，比较了这三种加固方法的效果，采用约束混凝土本构关系计算截面的抗弯强度，提出了三种加固方式的分析方法。

Test Study for Strengthening of Columns of RC Frame

This paper includes three of strengthening for twelves concrete frame test pieces ,and in experiment , the test pieces were Under static load test ,to get the nature joint operation of the present and existing strengthening columns ,and to distinguish the different effect of three strengthening mesures , calculate the section's strength of bending , and to put forward analgsis of three measures
