EXAMPLE 2. FORMAL STUDY METAL CONSTRUCTION

EXAMPLE 2: 'DESIGN OF A METAL STRUCTURE' 6 1. GENERAL DESCRIPTION 1.1 Geometry The metal shed under study consists of five frames of one span (7.05+7.05=14.10m). The frames are spaced 6.80m apart. The roof is pitched with a pitch of 5.33 (o). The ridge is at a height of 7.50m. The height of the poles is 6.50m. The frame structure is formed of steel frame, while the foundation is formed of individual reinforced concrete footings in both directions. For the complete geometry see the figure below: 1.2 Materials For the construction of all the members of the structure, steel grade S275 (Fe430) will be used. The modulus of elasticity is E=21000kN/cm2 and Poisson's ratio n=0.30. The specific gravity of the steel is taken to be 78,5 kN/m3. 1.3 Regulations Eurocode 0 (EC0, ENV 1990), for the determination of load combinations. Eurocode 3 (EC3, ENV 1993), for the dimensioning of the metallic members of the carrier. Eurocode 8 (EC8, EN1998), for seismic loads. Eurocode 2 (EC2, EN1992), for the dimensioning of the foundation.
