基于支持向量回归机的结构非概率可靠性分析
Structural non-probabilistic reliability analysis using support vector regression
摘要
Abstract
The regression technology of support vector machine(SVM) was introduced to analyze the non-probabilistic reliability of structures with implicit limit state function.Based on the fragment description model of unascertained information,the training data sampling method was proposed.The sample data in basic variable range was transformed to that in norm interval variable scale,and the dimensions of training samples were unified.So the stability of SVM could be assured.The algorithm was offered,and the training,test and prediction sample could be directly drawn in norm interval scales.So the sample drawing and Monte Carlo simulation became easier to realize.The accuracy and feasibility of this methodology were proved through two given examples.The problem of structural non-probabilistic reliability with implicit limit state function can be solved using this technique,and which is easy to use.关键词
