Abstract: Steel tanks that are welded to their base plates may become vulnerable to brittle fracture if the joints between base‐plate segments are defectively welded. A case history is discussed in which one of two large welded steel ...

Abstract: An organic cohesive material derived from soybeans was stored in a set of five tall unstiffened steel tanks that were equipped with conventional conical hoppers. Stagnant material caused by funnel flow compacted during hot ...

Abstract: Heavy concrete fragments crashing into the floor of a huge warehouse building, from an overhead precast structure, calls for an investigation to determine the cause of this phenomenon and stop it. Field observations show ...

Abstract: A rectangular reinforced concrete grain silo, supported by mill building columns, was impaired by cracking and spalling, as well as major distortions in the walls. A close inspection revealed major exposure and corrosion ...

Abstract: Failure of a poorly welded 2‐ft (0.61‐m) square cutout patch in the wall of a very large grain‐storage tank caused it to collapse. The tank split open first as a result of brittle fracture. The latter was affected by ...

Abstract: A tall reinforced‐concrete grain silo collapsed suddenly on a sunny, windless, day in the Midwest. Field observations and analysis showed that failure of the suspended steel hopper triggered the collapse. Attachment of the ...

Abstract: Steel tanks contained wheat in Zaïre, West Africa. They were provided with a conical hopper. After one hopper collapsed abruptly during emptying, inspection disclosed that failure had occurred at the bolted seams. Grain-induced ...
