摘要
研究在输入信息未知条件下识别结构物理参数的问题。根据建筑结构风荷载的作用特点,提出了一类时域识别算法,用于高层建筑结构的结构物理参数识别。文中对算法给出了理论证明。数值分析算例表明:不考虑量测噪声时,文中方法可给出结构参数的精确识别结果;
This paper focuses on the item of structural parameters identification without input information. An aglorithm named as uniform load statistical average method is proposed and its procedure is described based on the charicteristic of pulsation wind on structure. To give the algorithm a solid basis, a theoretical certificate is given in the paper. Further numerical studies show that the proposed algorithm is highly efficent not only for noise free situation but also for noise included situation. The new idea given in the paper seems to supply a hopeful way for parameter identification with unknown input.
