【Abstract】 Taking the health intelligent monitoring system of the roof-latticed truss structure of Shenzhen Citizen Center as an engineering background,a fuzzy pattern recognition method used to identify the stress field of the boxing brace steel brackets of roof latticed truss structure is systematically presented in the paper.After illustrating the basic idea of this method,the principle and the numerical analytical steps of the proposed method are demonstrated in detail.The numerical simulation of identification of instantaneous stress field of 25^th brace steel brackets in Shenzhen Citizen Center has been performed and the results show that the method is effective and reliable.更多还原
