Experimental Study on the Reshape of a Plate Girder under Loading(Welding Mechanics, Strength & Design)
Corrosion is one type of failures in steel bridges in service. In corroded part, as a result of rust, plate thickness decreases. In repair and/or strengthening works of these parts, heating works are used when corroded part is cut off using gas and additional members are connected using welding. H.T. bolts are also used to connect additional members. However, use of H.T. bolts inevitably accompanies by loss of section as bolt's holes in addition to cut off the section. Therefore, use of welding has not a little merit in repair works. This paper describes reshape works of a plate girder from uniform section to non-uniform section using gas cutting and welding under loading.
