Load–deflection curveRust elementFlexural strengthUltimate deflectionThis paper presents a finite element study of corroded concrete beam flexural behaviour in which the influence of the percentage of corrosion on the load鈥揹eflection curve was studied. CASTEM 2000 computation software was used and the...
The load–deflection curves of the test specimens are given in Fig.8. All of them were approximately linear after the first cracking. In RC beams with openings, the load abruptly dropped due to brittle shear failure. However, in RGm and RGh, the load–deflection curve became horizontal with ...
Fig. 6. Load-deflection curves. The formulation of the flexural crack caused a reduction in the beam stiffness, and the FRP or WWM handled the applied load. Inspection of Fig. 6 reveals that the slope of the first and second stage of the curve increased considerably and slightly, respectivel...
Simplified prediction of load deflection curve for RC beam strengthened by external steel plate The scope of the study is limited to RC beam strengthened by steel plates externally bonded to the tension face that exhibits the flexure mode of ... W Lin - IEEE 被引量: 2发表: 2011年 Displaceme...
Many experimental and analytical studies have been conducted with beam-column subassemblages composed of a two-span beam to investigate the progressive collapse resistance of RC frames. Most study results reveal a strength-decreased transition phase in the nonlinear static load-deflection curve, which ...

and the impact mechanism was analyzed.The results show that the concrete strain of the strengthened beam in high/low temperature is significantly greater than that in 20 °C ,the steel plate strain is obviously smaller, and the deflection is ...
Figure 14 shows the experimental load versus deflection curves for beams B1 and B2 as well as the computed load deflection curve. It can be seen that the failure loads of the beams B1 and B2 are different even though the beams are identical. This can only be attributed to experimental scatt...
Key words:reinforced concrete beam；CFRP；fatigue load；deflection 据相关统计显示，我国约有90%的桥梁结构采用钢筋混凝土结构形式［1］。钢筋混凝土桥梁在服役期内，会在车辆反复荷载作用下产生疲劳损伤，导致结构性能下降⑵，需对其进行加固补强。近年来，碳纤维增强复合材料(Carbon Fiber Reinforced Plastic，简称“CF...
major objectives of the research are to determine the load-deflection\\udcurve, crack pattern and effects of opening shape for each beam with and without CFRP strengthening as well as identifying the most effective strengthening method. ... CM Seow 被引量: 0发表: 2015年 Behaviour of RC Flat...
