Effect of skew angle on bridge deck behavior with different cross girder patterns

Bridges are common and important constructions to overcome different obstacles in any transportation network. Variations bridge types include variation span length, statical system, construction material, methods sustained loads. Choosing the suitable system is affected with several factors such as time, availability of materials, available budget, contractors’ background one most layout road network or outline beneath bridge. Skew bridges result from inclined intersection between axis below water stream. The famous problems that this inclination distribution loads among main girders bearings` reactions. Stiffness cross especially near skew edge affects noticeably girders. In paper, analysis medium RC girder deck will be proposed using angles (α) measured horizontal 20̊, 30̊, 40̊ 50̊ patterns. Analysis performed grillage model FEM software package. includes angles, patterns distributed gravity load observed outputs reactions at bearings bending moment values effect on introduced. these variables BM discussed extended paper work.
