基于分灾模式的抗震加固设计概念初探
|
摘要
在分析现有建筑结构抗震加固方法的基础上,引入结构分灾的设计思想,提出了基于分灾模式的抗震加固方法。说明了该加固设计方法的基本原则,分灾单元的设计要点,本加固设计方法不仅能够提高结构的承载力,而且能够提高提高结构的延性和耗能能力以及消减大震下的结构地震反应,为建筑结构加固设计提出了新的设计思路。本方法特别适用于由丙类提高为乙类的建筑物的抗震加固。
On the basis of analyzing the current ways of structure seismic strengthening and in accordance with the design idea of structure damage-reduction,the method of seismic strengthening which based on the damage-reduction mode was presented.The principles of the strengthening design and the main design points of the damage-reduction unit were illustrated.This method can improve the structure bearing capacitys,the structure ductility and the ability of cosuming energy as well as reduce the earthquake response of the structure when suffering the violent earthquake.A new thoughts of seismic strengthening of buildings was presented.This method is specially suitable for the buildings which seismic fortification category are raised from c to b.
