  1. 11. Serviceability assessment of footbridges when subjected to vibrations induced by running pedestrians

    University essay from KTH/Bro- och stålbyggnad

    Author : Javier Garmendia Purroy; [2017]
    Keywords : Footbridge; Running; Jogging; Load; Vibrations; Structural; Dynamics; Pedestrian footbridge interaction; Serviceability; Assessment; Gångbro; Löpning; Last; Vibrationer; Strukturdynamik; Bruksgränstillstånd; Bedömning;

    Abstract : Vibration serviceability in the design of footbridges is gathering enormous prominence as comfort restrictions get enhanced. Comfort verifications are often becoming critical when considering human induced dynamic loading on lightweight structures, which are increasing in slenderness and flexibility. READ MORE

  3. 12. Mass evacuation - human behavior and crowd dynamics - What do we know?

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Markus Friberg; Michael Hjelm; [2015]
    Keywords : Turbulence; stop-and-go waves; bottleneck; crowd crush; crowd disaster; sports ground; stadium; mass evacuation; human behavior; fire; guidelines; communication; simulation programs; pedestrian dynamics; Bradford City fire; Ibrox disaster; Hillsborough disaster; the Love Parade disaster; Technology and Engineering;

    Abstract : The field of mass evacuation has existed for a long time. Already during the Roman Empire era evacuation problematic was considered. In modern times the field has gained more attention during the last couple of decades, especially for sports grounds and stadiums. READ MORE

  4. 13. Modelling Pedestrian-Induced Vertical Vibrations of Footbridges

    University essay from Umeå universitet/Institutionen för fysik

    Author : Emma Zäll; [2015]
    Keywords : Footbridge; Pedestrian-induced; Vertical vibrations; Pedestrian-footbridge interaction; Structural dynamics; Crowd simulations.;

    Abstract : A pedestrian crowd walking on a footbridge causes the footbridge to vibrate. These vibrations become an issue of serviceability and can give rise to discomfort for the pedestrians, whereby they should, to as large extent as possible, be prevented. READ MORE

  5. 14. A Cohesive Downtown from a Knowledge City Perspective - A Study in Urban Planning

    University essay from JTH, Byggnadsteknik

    Author : Alma Jacobson; [2012]
    Keywords : Urban Cohesion; Knowledge City; Urban Planning; Innovation Engines; Public Spaces; 4th Urban Space; Copenhagenization; Jönköping;

    Abstract : The escalating urbanization process has given rise to various complications in the urban structure. One of the major issues is the one concerning urban cohesion. As modern cities are facing a transformation from industrial to knowledge societies, many aspects have to be taken into consideration in the planning of cities. READ MORE

  6. 15. Modelling near ground wind speed in urban environments using high-resolution digital surface models and statistical methods

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Lars Johansson; [2012]
    Keywords : Geographic Information System; spatial variability; GIS; digital surface model; wind speed; urban geometry; geomatics; geography; urban climate; physical geography; geografi; naturgeografi; geomatik; stadsklimat; bebyggelsegeometri; vindhastighet; digital höjdmodell; rumslig variation; geografiska informationssystem; Earth and Environmental Sciences;

    Abstract : Wind is a complex phenomenon and a critical factor in assessing climatic conditions and pedestrian comfort within cities. This master’s thesis attempts to quantify and model the relationship between near ground wind speed and urban geometry using two-dimensional raster data and variable selection methods based on Multiple Linear Regression.
