The paper describes an original technology used for onsite shear test. The test aims to determine the shear stiffness in both the principle directions of an auxiliary system employed during accelerated construction process of the prefabricated bridge. The auxiliary pier system is constituted by the coupling of two temporary truss towers working as auxiliary pier columns to carry and erect the prefabricated pieces during the bridge construction procedure. This experimental investigation permits us to redesign the whole temporary auxiliary systems affected by some faults in the flanged connections. A good correspondence between numerical and experimental investigation was obtained.

Abstract
The paper describes an original technology used for onsite shear test. The test aims to determine the shear stiffness in both the principle directions of an auxiliary system employed during accelerated construction process of the prefabricated bridge. The auxiliary pier system is constituted by the coupling of two temporary truss towers working as auxiliary pier columns to carry and erect the prefabricated pieces during the bridge construction procedure. This experimental investigation permits us to redesign the whole temporary auxiliary systems affected by some faults in the flanged connections. A good correspondence between numerical and experimental investigation was obtained.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
