The relationship between the lateral vibration of footbridge and the coefficients in Nakamura's model, including the rate of a pedestrian's lateral force, pedestrian density, rate of synchronized pedestrians, and pedestrians' attitude to large vibration amplitude, has been revealed, the simulation results demonstrate the validity of our theoretical analysis. The influence of the function to describe how pedestrians synchronize with the bridge natural frequency in Nakamura's model on lateral vibration of footbridge has been known. Our result shows that pedestrians are not always most likely to synchronize at the bridge frequency around 1.0Hz.","PeriodicalId":6340,"journal":{"name":"2011 International Conference on Electric Technology and Civil Engineering (ICETCE)","volume":"12 1","pages":"4743-4746"},"PeriodicalIF":0.0,"publicationDate":"2011-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81904356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The result shows that, with the increase of the traffic intensity, the turfgrass height and above-ground biomass decrease gradually. Compared with the control group, the decreasing amplitude of natural-artificial turf, A2, A4, A6 and A8, is smaller. The density, texture and color of every group are all reduced with the increase of traffic intensity, and the control group A0 is influenced most, with the highest change rate. In the natural-artificial turf, the natural turfgrass is protected by the artificial turfgrass, which makes the turf quality more stable.
