钢筋混凝土结构加固量分析及确定方法

Analysis and Method for Quantity of RC Structural Reinforcement

系统地分析了建筑结构加固的原因,主要讨论了钢筋混凝土梁、板、柱的加固。给出了三类加固量定义:荷载加固量、内力加固量、配筋加固量。并根据工程实际情况,对不同加固结构进行工况分析,结合规范给出了加固量统一计算公式。该加固量分析计算方法可以指导实际加固改造工程的设计。

Some structural strengthening reasons are analyzed systematically.This paper mainly discussed the strengthening method of reinforced concrete beams,slabs,pillars.Meanwhile,the definitions of the structural strengthening quantity were given;strengthening quantity of load,strengthening quantity of stress,Strengthening quantity of installing reinforcement.then according to actual circumstance of engineering,strengthening structures were carried on the work condition analysis.Based on the Code for Design of Concrete Structure(GB50010-2002), calculating formulas of the strengthening quantity were given,which may be served as reference for practices.
