Computational analysis of curved prestressed concrete box-girder bridges using finite element method.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The study employs finite element method to examine the effects of curve angle variations on the behavior of single and double-cell prestressed concrete box-girder bridges. A total of eighty bridge models were examined, featuring a range of curve angles from 0 to 60°, with increments of 12° between each model (0°, 12°, 24°, 36°, 48°, and 60°). The study revealed that bridges with curve angles of 24° or less exhibit minimal impact on forces, suggesting that they can be effectively treated as straight bridges for analytical purposes. The study revealed a marked change in structural response for bridges with curve angles greater than 24°, highlighting the influence of increased curvature on bridge behavior. A comprehensive evaluation was conducted to investigate the influence of changes in curve angles, span lengths, cell numbers, and span-depth ratios on structural forces and deflections under various load types, including dead, live, and prestressed loads. As the curve angle increases, a corresponding decrease in the flexural moment and vertical deflection is observed under prestressed loading conditions. Based on the analysis, it is reasonable to conclude that prestressed concrete box-girder bridges are best suited for applications involving higher curve angles.
