高效全预应力粘结复合一体化加固混凝土结构成套技术研究

Research on high performance prestressed reinforcement bonded composite integration technology system of concrete structure

钢筋混凝土结构加固存在着两大根本关键问题：一是“二次组合”,新老结构不能共同工作;二是结构“二次 受力”,新增结构应力应变滞后.本文主张在土木结构、建筑、交通桥梁等工程中应积极以全预应力粘结复合一体化 技术方法加固砼的梁、板、柱（墙）、节点等诸类结构构件,实现结构加固有效、加固髙效的根本目标.

There are two basic key problems in the reinforcement of reinforced concrete structures. First,the ＂two co^Ibinations,,,the new and old structures can not work together, two,the structure f,two times force＂,the new structure stress and strain lag. This paper argues that in civil structures, buildings,bridges and other transporta-tion projects should be in full prestressed composite reinforced concrete beam method integration technology, plates and columns （wall）,the node structure,realize the effective reinforcement structure,strengthening the fun-damental purpose of efficient.
