砖砌体结构加固中砼利用系数的探讨

THE DISCUSSION OF CONCRETE UTILIZATION COEFFICIENT IN STRENGTHENED BRICK MASONRY STRUCTURE

本文作者根据砖砌体和砼的应力应变关系及极限应变值，从理论上推导了后加砼与原砌体之间的应力应变关系，提出了新旧材料界限破坏的概念，并按此概念给出了轴心受压砖砌体加固中砼利用系数的确定方法。

Base on the stress strain relationship and ultimate strain of brick masonry and concrete,this paper from theory analyses the stress strain relationship between later concrete and original brick masonry,and presents a new concept of boundary fracture on new and old materials.Base on this concept,the method of deciding concrete utilization coefficient is given in axial compression brick masonry structure.
