Evaluation of human-induced vibration of continuous footbridges [PDF]
MATEC Web of Conferences, 2015 مع تطوير مواد البناء وإدخال الفولاذ والخرسانة عالية القوة، أصبح الاهتزاز الناجم عن الإنسان معيارًا سائدًا لتصميم جسور المشاة. في الوقت الحالي، تم تضمين مساحات أطول وجسور خفيفة الوزن في معظم اتجاهات التصميم. وهذا يؤدي إلى انخفاض الترددات الطبيعية للنظام والتي لها تأثير كبير على الأداء الديناميكي للجسور الخاضعة للأنشطة البشرية. على الرغم من أن تصميم جسور

Lock-in of the vortex-induced vibrations of a long tensioned beam in shear flow [PDF]
, 2011 The occurrence of lock-in, defined as the local synchronization between the vortex shedding frequency and the cross-flow structural vibration frequency, is investigated in the case of a tensioned beam of length to diameter ratio 200, free to move in both

Some relevant aspects of footbridge vibrations [PDF]
Facta Universitatis. Series: Architecture and Civil Engineering, 2002 Considering the contemporary structural inaterials that are becoming more resistant, having higher strength to weight ratio, and the fact that live load of footbridges is low, the design based on static analysis only, respecting ultimate limit states ...
