Artykuł prezentuje autorską metodę monitorowania przemieszczeń mostowych konstrukcji kolejowych. Wykorzystuje ona inklinometry i akcelerometr do pośredniego pomiaru przemieszczeń pionowych pod obciążeniem dynamicznym. Opracowany system monitorowania ciągłego jest wspomagany przez okresowe pomiary tachimetryczne, które służą do weryfikacji przemieszczeń statycznych. Przedstawiono opis działania systemu...
Global Positioning System (GPS) is being actively applied to measure static and dynamic displacement responses of large civil engineering structures under winds. However, multipath effects and low sampling frequencies affect the accuracy of GPS for displacement measurement. On the other hand, accelerometers cannot reliably measure static and low-frequency structural responses, but can accurately measure...
