摘　　要：将RBF人工神经网络理论应用于等高单层钢筋混凝土柱工业厂房的震害预测。在分析震害特点的基础上,将震害影响因子分为精确性和规律性两大类,提出以地震反应指标、天窗类型、支撑情况、建筑材料作为主要的影响指标。然后将震害等级作为输出结果,构造了震害预测的非线性预测模型。通过对52个实际震害实例的检验,网络的准确率高,可见该模型是有效可靠的。The RBF artificial neural network is applied to predict seismic damage of single-story reinforced concrete industrial building.Based on the analysis of characteristics of seismic damage,it is found that earthquake response index,type of sky light,bracing system and building material are the ma in factors affecting seismic damage.The four factors can be classified into two types：precise factors and regular factors.The corresponding spans of factors are suggested and applied to engineering examples.Thus the RBF artificial neural network is developed,with factors affecting seismic dam age as input and seismic damage grade as output.It was verified by 52 engineering examples.It is concluded that the RBF artificial neural network developed in this paper is applicable to predictseismic damage of single-story reinforced concrete industrial building.
