［摘要］對(duì)因混凝土強(qiáng)度不足而需加固的框架柱，采用高強(qiáng)材料置換其外周截面是一種簡(jiǎn)便、實(shí)用的方法。結(jié)合加固設(shè)計(jì)與施工經(jīng)驗(yàn)，研究了該方法的基本原理、應(yīng)用條件與施工技術(shù)，推導(dǎo)了保留芯柱截面的計(jì)算方法，并給出了工程應(yīng)用實(shí)例。

Abstract:For those frame columns, the concrete strength of which is obvious deficient, the simple and convenient reinforcing method to replace the outer section by higher strength materials is introduced. Based on the practical experience, study results on the basic principle, the applicable conditions and the technology in practice of this method are explained. Then the formulae of determining the remained core section of the column section are given with an applied example in detail.
Keywords:high strength replacement material；outer replacement section；concrete frame column； chisel；remained core section
