摘要
在不同温度下对预应力碳纤维(CFRP)板加固的桥梁进行观测;分析温差对预应力CFRP板的应力损失;通过大量的数据拟合了CFRP板应变差与温差的计算公式,并根据分析结果提出了有实际指导意义的建议。
A bridge strengthened with prestressed CFRP plates was observed , and the stress loss of the prestressed CFRP plate caused by temperature difference was analyzed , fit the calculation formula of strain difference and temperature difference was also fit based on a large amount of data , and then it was put forward practical suggestions according to the results of the analysis .
