混凝土疲劳强度折减系数的模糊比较
|
摘要
设计了混凝土疲劳专用试件形状,阐述了疲劳参数的确定方法,进行了轴向拉-拉和轴向拉-压疲劳试验,在比较了多种曲线拟合方法后,最后选择了多元线性回归分析方法并建立了疲劳方程。本文也详细研究了二元模糊比较数学模型及其算法,并首次运用该算法对各种规范的混凝土疲劳强度折减系数进行了比较分析,发现了本试验与文献的接近程度,为相关试验及相关工程设计提供了参考。
devises a specimen used in concrete fatigue test only, and expounds a method of concrete fatigue basis parameters confirmed,and tests concrete fatigue of axial tension-tension and tension-compression too, after being compared multiple curve fitting, finding that multivariate linear regression analysis is better, and founds fatigue equation with it in the end; at the same time, minutely studies binary fuzzy comparison modeland its algorithm too, and with which compares the discount coefficient of concrete fatigue strength with other code recommendations for the first time, finding the test is close to other literatures, and provides a reference for some mutual test and engineering design.
