适用范围：(1) Part 4.1 of Eurocode 3 provides principles and application rules for the structural design of steelsilos of circular or rectangular plan-form, being free standing or supported.(2) The provisions given in this Part supplement modify or supersede the equivalent provisionsgiven in EN 1993-1.(3) This part is concerned only with the requirements for resistance and stability of steel silos. Forother requirements (such as operational safety, functional performance, fabrication and erection,quality control, details like man-holes, flanges, filling devices, outlet gates and feeders etc.), see therelevant standards.(4) Provisions relating to special requirements of seismic design are provided in EN 1998-4, whichcomplements or adapts the provisions of Eurocode 3 specifically for this purpose.(5) The design of supporting structures for the silo are dealt with in EN 1993-1-1. The supportingstructure is deemed to consist of all structural elements beneath the bottom flange of the lowest ring ofthe silo, see figure 1.1.(6) Foundations in reinforced concrete for steel silos are dealt with in EN 1992 and EN 1997.(7) Numerical values of the specific actions on steel silos to be taken into account in the design aregiven in EN 1991-4 Actions in Silos and Tanks.(8) This Part 4.1 does not cover:− resistance to fire;− silos with internal subdivisions and internal structures;− silos with capacity less than 10 tonnes;− cases where special measures are necessary to limit the consequences of accidents.(9) Where this standard applies to circular planform silos, the geometric form is restricted toaxisymmetric structures, but the actions on them may be unsymmetrical, and their supports mayinduce forces in the silo that are not axisymmetrical.
