Dynamic Analytical Modeling of Horizontal Outline Turn of T-Girder Simply Supported Bridge

Layout line of bridge structure is a direction which used to define the horizontal and vertical alignment structure. The objective this study evaluate optimize different designs outline turn compare results with layout straight using dynamic analysis according finite element method. Dynamic showed that most models have converging values natural frequency except Model No. F. it explains higher rate 5.10Hz within model maximum value loaded equal 6.35 Hz for I (Straight - curve right left straight). A appears minimum 3.56Hz. indicates has high vibration state effects on stiffness flexibility downward acceleration 3.55m/s2. upward deflection 1.84mm 4.07mm respectively in G, indicating will easy deflect under traffic loads. It can be concluded bridges F, H, than frequency. Therefore, these lower bearing capacity other. recommended optimum design more elasticity.
