FIELD STRESS MEASUREMENTS OF A PLATE GIRDER BRIDGE CARRYING A 116 TONF TRUCK

Field stress measurement was carried out on a plate girder bridge of 27.9 m span made from weathering steel using a 116 tonf special truck. The bridge spanned two factories of a steel mill, and has been used to transport coils of steel plates. The thickness of the concrete slab was increased to 35 cm to support the heavy trucks. Strain gauges were attached to the tension flanges, diagonal bracing and the upper ends of vertical stiffeners. Strains under static loading, moving loading and strain histograms for 24 hours were measured. The strain measurement of static and dynamic loading showed that the loads were well distributed between the four girders, and the measured stresses were within the allowable limit, provided that the special truck passed over the centre of the bridge.
