Abstract:
Gives material, design, and construction requirements for concrete silos, stave silos, and stacking tubes for storing granular materials. It includes design and construction recommendations for cast-in-place or precast, and conventionally reinforced or post-tensioned, silos. Silos and stacking tubes are special structures, posing special problemsnot encountered in normal building design. While this standard refers to "Building Code Requirements for Reinforced Concrete (ACI 318)" for many requirements, it puts forth special requirements for the unique cases of static and dynamic loading from funnel flow, mass flow, concentric flow, and asymetric flow in silos and the special loadings on stacking tubes. The standard includes requirements for seismic design and hopper bottom design. Appendixes provide values for overpressure and impact factors from stored materials.
