Temporary pier for the launch of the Ihsaniye viaduct
Detailed design of two temporary piers for the launch of the Ihsanye Bridge.
The incremental launch of the Ihnsaniye Bridge in Turkey needed the construction of two temporary piers to allow the crossing of the span with a maximum span of 80m (typical span around 50m). The bridge has two specular and independent decks with a CAP box section approximately 21m wide.

The temporary piers are about 15 m high and consist of 4 double T columns linked together by a reticular structure. At the top, two high-inertia beams support the sliding sleds and the lifting cylinders and, in turn, rest on diagonal elements that carry the load on the columns, placed at a reduced distance between the centers with respect to the supports.

The whole system is designed to minimize the deformations under the reaction transferred from the bridge because the prestressed concrete deck is very rigid and therefore extremely sensitive to differential settlements.
