摘要

本文依据模糊模式识别理论,以深圳市民中心屋顶网架结构的智能健康监测系统为背景,系统地介绍了屋顶网架结构支承箱型钢牛腿应力场的模糊模式识别方法。文中,在说明了方法的基本思路的基础上,详细介绍了方法的基本原理和仿真分析的步骤。并通过对深圳市民中心25号钢牛腿应力场识别的仿真,验证了方法的效果和可靠性。
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.
