| 預應力碳纖維片材加固的橋梁使用階段應力分析初探(49 卷) |
| 英文標題 |
| Elementary discussion on stress analysis during operating stage of bridge strengthened by prestressed carbon fiber piece |
| 摘要 |
| 預應力碳纖維加固技術因其能明顯提高受彎構件在使用階段的承載力（開裂彎矩、屈服彎矩）和開裂以后的剛度，并且抗腐蝕、耐疲勞而逐漸成為研究的熱點。參照設計規(guī)范，初步提出了預應力碳纖維片材加固鋼筋混凝土梁在使用階段的應力計算公式，并針對某一實橋，借助設計軟件Midas |
