In the early stage of the design process,the design of tall building is a complex work. It needs various knowledge and professional experience for the structural design. A way concerned about the choice of structural styles is put forward based on radial basis function neural network ( RBFNN) in this paper. The qualities of the RBFNN,high-nonlinear,high-permissibility of error and high-robustness,self-adaptability,online work,and so on,are adequately used in the research. And,it is concluded that RBFNN runn...
