This paper describes the design and structural solution of an office building situated above a metro station, using a combination of concrete and steel structures. The concrete frame building spans across the tunnel using a three-truss steel bridge, suspended from its fourth floor. The bridge supports a total of 14 concrete floor slabs. The main factors influencing the design process are described, including choice of the bridge supports, measures to minimise the trusses deflection and reduction of movements and forces in the concrete structure. The overall composite action of the steel and concrete members is also described, using force and moments diagrams to illustrate the design options considered. The final solution, together with the details of the associated savings of rolled steel weight, is presented.
