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 ...
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 beam's ductility can be quantified by measuring the mid-span deflection relative to the steel yield point. This measurement was established by examining the corresponding flexural strain gauge readings and load–deflection curve, as well as indicating the level of plasticity that a beam can ...
3.1. Load–deflection curves The load-deflection curves of all tested beams are presented in Fig. 7a–d. All curves in Fig. 7 were characterised by three distinct stages (ascending branches with decreasing slope) up to the maximum load: (1) Stage I: un-cracked beam; (2) Stage II: deve...
Results of RC-1 beam: (a) FEM failure pattern, (b) experiment failure pattern, and (c) load-deflection response. The analysis results show that the concrete adopts the total strain crack model and the steel bar adopts the von Mises model, which can well simulate the control members. 3.5...
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 ...
For the post strength point, this study modified the point where final collapse and lost of gravity load capacity occur as suggested by ATC-40.The calculated load-deflection curve up to ultimate point shows reasonable correlation with the previous reported experimental results. The negative slope of...

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...
