Place: Prague 5, Holeckova st., Czech Republic
Description:
Objects SO01 and SO02 of Sacre Coeur II Residence cross in plan the tube of the Strahov tunnel. As the load bearing capacity of the tunnel in vertical direction is limited, it was designed to span the tunnel tubes by the steel bridges which forms the integral part of three respectively four stories of the objects. Subsequent stories are designed with reinforced concrete load bearing structure. The principal steel structure of both objects is formed by two huge truss girders with statical height equal to 9,2m and span 52,5m for the SO01 object and statical height equal to 6,4m and span 45m for the SO02 object. Main girders are simply supported on RC structure founded on piles next to the tunnel tubes. Perpendicularly to the mail girders there are the secondary truss girders whose geometry on individual axes varied depending on civil engineering requirements and general disposition relations. Transversal girders are mostly welded truss structures. Floor decks had the composite steel-concrete structure. The chosen assembly procedure of main girders was really unique. They were welded up in the horizontal position from the assembly parts and using the special auxiliary pin steel structure and the heavy crane they were rotated to the vertical position in which they were ensured by oblique struts.
