高强材料置换截面加固混凝土框架柱的研究

Research on reinforcing frame columns in concrete structures by outer section replacement with high strength materials

对因混凝土强度不足而需加固的框架柱,采用高强材料置换其外周截面是一种简便、实用的方法。结合加固设计与施工经验,研究了该方法的基本原理、应用条件与施工技术,推导了保留芯柱截面的计算方法,并给出了工程应用实例。

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.
