混凝土框架结构“不入户加固方法”研究

Study on "Non-Household Reinforcement Method" of Concrete Frame Structure

对于混凝土框架结构,目前普遍采用直接对原建筑结构的梁柱进行加固的方法,但是,这种直接入户的加固方法在施工过程中严重影响建筑物的使用功能。鉴于此原因,国外研发了“不入户加固”的设计方法,紧接着,国内提出了在原建筑物外部增设结构承担分灾任务的思路。本文在以上的研究基础上,提出在减震分灾模式下混凝土框架结构“不入户加固”方法,并进行对比研究。

At present,the concrete frame structure generally adopts the method of directly strengthening the beams and columns of the original building structure.However,this reinforcement method of directly entering the house seriously affects the use function of buildings in the construction process.In view of this reason,foreign countries have developed the design method of“non-household reinforcement”,followed by the domestic idea of adding a structure outside the original building to undertake the task of damage-reduction.Based on the above research,this paper proposes the method of“non-household reinforcement”for concrete frame structures under the mode of shock absorption and damage-reduction,and conducts a comparative study.
