粘钢加固钢筋混凝土T梁模型裂缝试验研究

Research on crack experiments of T-shaped model of strengthened reinforced concrete with gluing steel

针对粘贴钢板对钢筋混凝土T梁裂缝的影响开展研究,以3片T梁模型试验为基础,研究了钢板数量对钢筋混凝土T梁开裂弯矩、裂缝间距、裂缝宽度的影响,并依据试验结果,给出了相应的计算方法,对工程实践具有一定指导意义,并为今后进一步分析提供参考依据。

According to the research on the influence of adhesive steel on reinforced concrete T-type beam cracks, the paper studies the influ- ence of the amount of steel sheets on the cracking moment, the crack interval, and crack width by taking three T-type beams＇ model tests as the foundation, and provides respective calculating methods according to the tests＇ results, so it directs the engineering practice and provides some reference for further analysis in future.
