Dataset for CONCRETE CRACKING AND DEFLECTION ANALYSIS OF RC BEAMS STRENGTHENED WITH PRESTRESSED FRP REINFORCEMENTS UNDER EXTERNAL LOAD ACTION

Current dataset provides experimental research and calculation data of crack widths for the manuscript CONCRETE CRACKING AND DEFLECTION ANALYSIS OF RC BEAMS STRENGTHENED WITH PRESTRESSED FRP REINFORCEMENTS UNDER EXTERNAL LOAD ACTION. It was found that bond behavior of the beams strengthened with initial moment and without it is not the same and the partial rigidity of the concrete-FRP joint should be taken into account for a prediction of element deformations.

当前数据集为论文《外部荷载作用下预应力纤维增强复合材料筋（FRP筋，Prestressed Fiber Reinforced Polymer Reinforcements）加固钢筋混凝土梁（RC梁，Reinforced Concrete Beams）的混凝土开裂与挠度分析》（CONCRETE CRACKING AND DEFLECTION ANALYSIS OF RC BEAMS STRENGTHENED WITH PRESTRESSED FRP REINFORCEMENTS UNDER EXTERNAL LOAD ACTION）提供了裂缝宽度的试验研究与计算数据。研究发现，施加初始弯矩加固的梁与未施加初始弯矩加固的梁之间的粘结性能（bond behavior）存在差异，且在预测构件变形时需考虑混凝土-FRP界面的部分刚度（partial rigidity）。
