The paper describes an original technology used for onsite shear tests. The test determines 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. By this experimental investigation we are able 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. |
