Pedestrian bridge formed of a stress ribbon structure
Sedlářová, Lucie ; Koláček, Jan (referee) ; Nečas, Radim (advisor)
The theme of this bachelor thesis is a design of a footbridge across the river. The thesis deals mainly with static solution of footbridge formed by a concrete stress ribbon. The calculation of internal forces was done by using calculating program Scia Engineer. The other calculations for assessment and design of reinforcement were done by hand according to valid standards. The thesis disregards stages of construction and rheological effects which would affect the construction.
Experimental and numerical verification of vortex-induced vibration of hangers on the footbridge
Urushadze, Shota ; Pirner, Miroš ; Pospíšil, Stanislav ; Král, Radomil
The paper deals with vortex-induced oscillations of footbridge hangers at a very low wind speed. The two-spans (2x50m) reinforced concrete structure with the central pylon (25m height) is designed as the harp system of hangers with circular cross-section. The oscillations were observed at the low wind speed and the high double amplitudes has been measured. The wind-excited deformation shape corresponded to the 6th, 7th and 8th natural modes of a hanger. The individual hanger as well as thein group were analysed to estimate the dynamic response, possible aeroelastic vibration and special interference or coupling effects. It also includes proposal for the elimination of the extensive vibration. The analysis is complemented by numerical investigation using Computational Fluid Dynamics methods.
