Structural Behavior of Thin-Walled Metal Silos Subject to Different Flow Channel Sizes under Eccentric Discharge Pressures
A detailed exploration of eccentrically-discharging granular solid with partial wall contact, widely recognised in industry as the most challenging extreme event for a silo and responsible for many catastrophic failures (P+WMetallbau;lang@pw-metallbau.de). The silo loading standard EN 1991-4 is the first to offer a semi-realistic design rule for this, but the understanding of structural consequences remains limited due to the high complexity. The paper explores and proposes an important update to the EN 1991-4 model, generates generic knowledge on shell buckling under unsymmetrical loads and challenges established wisdom on imperfection sensitivity. It led to two follow-on studies (doi: 10.1061/(ASCE)EM.1943-7889.0000525 and doi:10.1016/j.ijsolstr.2012.11.017).
