Steel structures of Larisa stadium roof are formed by couples of plane-truss cantilevers.
Distance between the plane-trusses is 4.7m and the step of couples is (9.4m+4.7m) = 14.1m. Each couple of main trusses is internal braced and is connected in the joints of lower layer by transversal posts and diagonals.
Each North/South truss has a global length of about 24m and a cantilever length of about 13.5m. It has the internal support on a steel column (with transversal “X” bracing) and the external support on a concrete structure. The longitudinal distance between supports is about 7m.
Concrete structure and the transversally braced columns give the necessary restraints to horizontal actions.
