Analysis of elastic behaviour of steel shell subjected to silo loads

摘要

The paper presents theoretical and numerical studies of the behaviour of steel shells sub- jected simultaneously to internal pressures and frictional forces (distributed forces tangential to the shell surface). The type of combined loading used for this analysis (horizontal pressure and wall frictional pressure which occur in the silos) is given in Eurocode 1 Part 4 [Eurocode 3, Design of steel shells, CEN/TC250/SC3. Draft prENV, 1993.] and in the French draftcode P22-630 [Norme Francaise P22-630 edition AFNOR, 1992.] the cylindrical shell is symmetri- Cally loaded (symmetrical filling and discharge).
