Title: Experimental Determination of Effective Weight of Stored
Material for Use in Seismic Design of Silos
Author(s): Ernest C. Harris and John Duris von Nad
Publication: Journal Proceedings
Appears on pages(s): 828-833
Keywords: earthquake resistant structures; granular materials; silos; structural design; weight (mass).
Abstract:This paper shows the results of shaking tests on two relatively rigid steel model silos filled with sand or wheat, or empty. Graphs recording driving force and displacements provided data for analytically computing the percentage of total weight of stored material that should be considered effective when computing lateral seismic force to use in structural design. The effective-weight coefficients thus computed from the experimental data appear to confirm the 80-percent value given as a requirement by the "Standard Recommended Practice for Design and Construction of Concrete Bins, Silos, and Bunkers for Storing Granular Materials (ACI 313-77)(Revised 1983)."
