Abstract
The construction of span-skewed bridges has become widespread worldwide and in Turkey. This article focuses on the structural behavior of simply supported prestressed concrete bridges with varying skewness angles. Specifically, supported I girder pretensioned prestressed concrete bridges are investigated using different models (five models) with skewness angles 0° - 21°- 37.6°- 57°–66.6°. These models are analyzed using the Midas Civil software to analyze and design various bridge components and types through the finite element method. This method employs the most commonly accepted codes worldwide. This research showed that shear forces and bending moments were significantly affected by increasing the degree of skewness angle when it exceeds 37.5°. External I-girders behavior was similar yet inversely proportional behavior. Internal I-girder behavior was also identical but inversely, too.
