Abstract: A new method using the Global Positioning System (GPS) was proposed to directly measure the suspension bridge girder displacements induced by wind forces. The field measurements were carried out using this system on an ...

Abstract: A new type of steel and concrete composite bridge with steel U-shape girders has been proposed. The U girder can be cold formed from one steel sheet, and the amount of welding required is substantially small and mass ...

Abstract: It was observed on a pedestrian cable-stayed bridge that the girder vibrated laterally with a frequency of about 0.9 Hz, the natural frequency of the first lateral mode, when a large number of people crossed the bridge. ...

Abstract: It was found from field surveys that suspension bridge cables were under severe corrosion environments due to the water and high temperature inside the cable. Corrosion environments depended on the wire positions inside ...

Abstract: Bending behavior of steel pipes filled with ultralight mortar was studied by bending tests using a steel pipe, steel pipes filled with ultralight mortar, and steel pipes filled with light aggregate concrete and normal ...
