钢纤维水泥基复合材料增强作用的理论研究

Theoretic Study on Complex Reforcement Affect in Steel Fiber Cement Base

本文全面考虑了纤维的阻裂作用和复合增强作用.并以损伤力学为基础对钢纤维混凝土材料的受力工作过程进行了研究.不仅推出了初裂强度、极限强度的计算公式,而且还给出了钢纤维混凝土的损伤本构方程。

In this paper,the actions of fiber prevention crack and complex reforcement are considered comprehensively.Based on the harm mechanics,the whole forced process of steel fiber concrete is studied.The calculation formulae of initial crack and limit strength are derived.The foundation equation of harm mechanics of steel fiber concrete is given here.
