采用外粘钢加固法对偏心受压框架柱进行加固设计的探讨

Review of Reinforcing Frame Pillar Pressed by Far Away Eccentricity by Applying External Adhesion Steel Reinforcement

《混凝土结构加固设计规范》已于2006年11月1日开始实施。该规范必须也必然与已有的《混凝土结构设计规范》有着基本的相容性。笔者以一个混凝土柱的结构加固设计验算实例,对建设部建筑物鉴定与加固规范管理委员会编写的《加固计算例题》,作一种类型(偏心受压构件)的设计计算范例的补充;同时,对《混凝土结构加固设计规范》中关于"外粘型钢加固法"的偏心受压构件的计算公式中存在的缺陷提出看法和加以纠正,并与从事结构加固行业的专家和技术人员共同商讨。

“Reinforcing Design Specification for applicable concrete structure ” has been carried out since November 1,2006, which also certainly has the foundational compatibleness with “Design Specification for the Concrete Structure”. Taking one reinforcing design calculus of concrete frame column structure as an example, we have made up one type of design calculation case （ eccentric compression component） for “reinforcing calculation example” republished by Building Identification and Reinforcing Specification Management Committee, Ministry of Construction ; Meanwhile, we have given some opinions and corrections for the defects existing in the calculation formula for the eccentric compression component of outer sticking steel reinforcing method of “Reinforcing Design Specification for the concrete structure”, and consulting with the specialists and the technicians engaged in the structural reinforcing industry.
