    Title: Experimental and Analytical Evaluation of Reinforced Concrete Girders under Low-Cycle Shear Fatigue Author(s): Richard W. B. Forrest, Christopher Higgins, and A. Ekin Senturk Publication: Structural Journal Volume: Issue: 2 Appears on pages(s): Keywords: bridge; fatigue; girder; reinforcement steel; shear. Date: 3/1/ Abstract: Cited by: 4. The tabulated results of the fatigue tests can be found in Appendix B. Simi- larly, the data, none of which represent a failure, for the Cate- gory Eâ ² details is shown in Figure Specimen 1D/R-2 Specimen 1D/R-2 was a welded plate girder specimen (Plate Girder A, Type 1) used to investigate the effect one D/R cycle has on the.

    of combined shear and bending and post buckling behavior. Herein, the study aims at investigating the effect of combined shear and bending on the stability of tapered web plate girders, including geometrical parameters such as the web and flange slenderness, as well as, the tapering ratios. Finite element analysis Elastic buckling strength. Introduction. Bases of Design. Buckling of Wide Flanges. Bending Strength of Box Girders. Nominal Shear Strength of Box Girders. Strength of Box Girders under Combined Bending, Compression, and Shear. Influence of Torsion on Strength of Box Girders. Diaphragms. Top-Flange Lateral Bracing of Quasi-Closed.

    As a result, NCHRP Project was initiated with these objectives: â ¢ Determine the relative effects of repeated damage and sub- sequent heat-straightening on the fatigue and fracture per- formance of steel girders. â ¢ Identify and quantify the material and process parameters that may affect the fatigue and fracture performance of heat. the web plate. To investigate the behaviour of perforated plate girders with inclined intermediate stiffeners under shear load, an experimental setup had been developed. Based on the available local facility, the test girders were tested using a self-straining testing frame. .

From the static ultimate tests it is concluded that Basler's tension field theory can be used to predict the ultimate load of hybrid plate girders under combined bending and shear.

Experimental tests included four small-scale tapered steel plate girders. Research was focused on both, critical shear load and ultimate shear resistance.

Moreover, the post-buckling behaviour of tapered plates was by: girders under the general loading of bending moment, shear and torque. Treatment of the individual components of the ship hull girder is the same as in the previous formulation.

This report covers the third phase of the project, the experimental test program of which 'Was carried out at College. modern plate girders are, fabricated by welding together two flanges, a web and a series of transverse stiffeners [1].

Flanges resist the applied moment, while web plates keep the relative distance between anges and resist fl shear. In most practical ranges, the induced shearing force is relatively lower than the normal flange forces.

The focus of this study is to investigate the behavior of trapezoidally corrugated-web plate girders (CWPG) under fatigue loading by means of evaluating their fatigue life under different stress ranges. The test girders failed by fatigue cracks, which started at the weld between the web and the tension flange near the web fold line.
