EXAMPLE 3. NON-STANDARD STUDY METAL CONSTRUCTION
EXAMPLE 3: 'DESIGN OF A METAL STRUCTURE' 6 1. GENERAL DESCRIPTION Geometry The metal structure under study consists of three levels with different floor plans (1 h Level 3.80m, 2 h Level 6.70m, 3 h Level 9.50m). The frame structure is formed by a steel frame, while the foundation is formed by individual reinforced concrete footings and connecting beams in both directions. For the complete geometry see the figure below: 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. 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.
