EXAMPLE 3. NON-STANDARD STUDY METAL CONSTRUCTION

EXAMPLE 3: 'DESIGN OF A METAL STRUCTURE' 7 Cross sections Pillars: HEA220 Main beams: HEA200 Secondary Beams: IPE200 Loading - analysis assumptions Dynamic Spectral Method with homosynchronous torsional pairs. The loadings according to the above analysis method in SCADA Pro are as follows: (1) G (permanent) (2) Q (mobile) (3) EX (epicyclic loads, earthquake forces at XI, from dynamic analysis). (4) EZ (epicyclic loads, ZII earthquake forces, from dynamic analysis). (5) Erx ± (epicentric torsional moment loads resulting from the epicentric forces of the earthquake XI displaced by the random eccentricity ±2eτzi). (6) Erz±(epicyclic torsional moment loads resulting from the epicyclic forces of the earthquake ZLI displaced by the random eccentricity ±2eτxi. (7) EY (vertical seismic component -earthquake by y- from dynamic analysis). To these, for this example, we will add the 3 below: (8) S (snow) (9) W0 (wind in direction x) (10) W90 (wind in the z direction) In the seismic analysis only the permanent and mobile loads are involved, not snow and wind loads which are taken into account in another "simple" static analysis scenario without earthquake (see Analysis). The values of snow and wind loads are arbitrarily taken without the exact calculation as required by Eurocode 1, for the sake of simplifying the example. On the contrary, the action coefficients ψ0, ψ1, ψ2 are determined exactly as prescribed by Eurocode_0. Comments All the commands used in this example, (and all the other commands in the program) are explained in detail in the Manual that accompanies the program.
