温差对预应力碳纤维材料板加固桥梁结构的应力损失分析
ANALYSIS OF STRESS LOSS OF PRESTRESSED CFRP PLATE STRENGTHENED BRIDGE STRUCTURE CAUSED DUE TO TEMPERATURE DIFFERENCE
-
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。Abstract: 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.
