摘要
本文研究了如何用谱分析方法进行建筑物原型观测资料的分析处理，对应用中所面临的困难采取了三种不同的方法加以处理。通过补偿模型来提取定量分析（如统计模型）建模后残差部分中的有规律成份即补偿项，加到原模型中来提高预报精度和结构性态评价的准确性。通过实例计算证明了补偿模型的合理性和可行性。
Introduction of spectrum in the appliance of the structural prototype observed data process is studied in the paper, three different methods are adopted in solving the facing problems in order to extract the regular part called supplementary item from the residue series, which is got by modeling. Supplementary model is obtained by attaching the supplementary item to the original model, this model has been attested by the real project to have the ability to promote the improvement of predicting precision and the exactitude in evaluating the structural behavior.
