Abstract
This is the first time that the landscape footpath is realized on the suspension monorail system. To study the comfort of pedestrians on the landscape footpath when the vehicle passes, the dynamic responses of the track beam and the landscape footpath at different speeds were analyzed using the established vehicle-bridge dynamic analysis model. To evaluate the comfort of pedestrians on the landscape footpath, two indexes, Root Mean Square (RMS) value of acceleration (ISO 10137) and peak value of acceleration (EN 03), were adopted. Results show that the displacement and acceleration responses of landscape footpath and track beam are obviously different. Vertical displacement of the track beam is much larger than that of the landscape footpath due to the eccentric load of vehicles. Due to the displacement and rotation of the structural components which support the landscape footpath, the lateral response transferred to the landscape footpath would be slightly weakened. Maximum RMS values of the lateral and vertical acceleration of landscape footpath are 0.162 m/s2 and 0.169 m/s2, respectively, which meet the requirements of ISO 10137. Peak lateral acceleration is 0.546 m/s2, which reaches CL3 standard, and the peak vertical acceleration is 0.548 m/s2, which reaches CL2 standard. Lateral comfort is slightly worse than vertical comfort.
Highlights
Monorail transit system regards the strip beam as the pathway, where the vehicles ride on the beam or are suspended under the beam. e first suspension monorail system was built in Wuppertal in Germany along the river in 1901
The pedestrian comfort of the landscape footpath paved on the suspension monorail beam meets the relevant requirements, and the lateral comfort is slightly worse than the vertical comfort
Under the background of the first practical application of the landscape footpath paved on the suspension monorail system, the paper analyzes the dynamic responses of track beam and landscape footpath of the suspension monorail at different vehicle speeds by establishing the monorail vehiclebridge coupled system. e pedestrian comfort level on the landscape footpath during the time in which the vehicle is passing the bridge is evaluated. e main conclusions are as follows: (1) e dynamic response of the landscape footpath is obviously different from that of the track beam
