骨料级配对橡胶混凝土梁损伤分形分析的MATLAB实现

分形维数能够表征自然形态的某些特征,利用MATLAB的简单操作可以快速计算出原图形的盒维数;利用MATLAB计算三种不同级配粗骨料橡胶混凝土梁破坏状态的盒维数得知,CRC小为最优级配;分析试验梁各级荷载下的盒维数发现构件损伤演化过程是一个增维的过程,从某种意义上揭示了橡胶混凝土构件损伤及其演化发展的特性,推动了橡胶混凝土结构的损伤研究。

The Aggregate Gradation Crumb Rubber Concrete Beam Damage Fractal Analysis and Realization of MATLAB

The fractal dimension can characterize some of natural features. By using MATLAB, the box-counting dimension of initial image can be calculated quickly; Calculating the box-counting dimension of three different gradations coarse aggregate crumb rubber concrete beams in damaging state based on Matlab, so small particle size of coarse aggregate gradation is the best for CRC; With the increase of load; Analysising the number of the box-counting dimension of the surface crack of test beam at all levels under the load increases indicates that the damage evolution process is a process of increasing dimension, which revealed the relationship between the damage and evolution of crumb rubber concrete in a sense, promotes the study of damage of the crumb rubber concrete structures.
