The properties of high-strength concrete(HSC) was studied after high temperature,the main factors influencing the concrete structure fired was analyzed,and the strength damage coefficient,durability damage coefficient,addition,the spalling degree and crack width of HSC are chosen as the criterion indices for concrete structure classification.A HSC by fired evaluation method was established,optimized its project direction used genetic algorithm,and the model is applied to classifying in an example.The evaluation results are accurate,this method is simple,and some errors were eliminated because of the subjective factors for traditional methods.Projection pursuit is a new evaluation method of judging and classifying of the HSC by fired,it has provided scientific basis to diagnosis,evaluation,repairing and strengthening for HSC structure damage by fired.
