摘要
如何根据一定时间内预应力损失的实测资料确定预应力长期损失是一个重要的课题。本文根据灰色系统理论中的预测模型GM(1,1)和残差GM(1,1)模型,提出了一种新的预测预应力长期损失的方法。实例分析表明,该方法的准确性是令人满意的。
An importance problem is how to determine the time-dependent prestress loss by using the data of beam test during confined time. In this paper, a new method of predicting the maxim prestress loss, based on the GM(1,1) model and residual error GM(1,1) model in the grey system theory is presented. The practical examples show that the method has satisfied accuracy.
