Network arch bridge : Optimization of the arch applying simple loads
Master's Thesis Civil and Constructional Engineering BYG508 - University of Agder 2019 ; This master thesis gives insight in structural behavior of network arch bridges. When designed with circular arches the bending moments tend to rise near the bridge ends. As suggestions for improving this problemtwo alternative arch geometriesare investigated; arch with elliptical shape anda three-center arch shape. The arch geometries are modelledwith different radius ratios.In addition,different variables are changed on the models which includes; arch rise, hanger inclination, number of hangers and the transition point between the curvatures.Two-dimensional numericalcalculations are doneusing structural software. Only simple loads are applied to the bridges as the task is based om comparing the different arches.After analyzing the results, it is evidentthat a reduced radius ratiofor both elliptical arches and three-center arches improves the bending moments near the arch ends.
