Determination of loads play significant role in the design of silo. The silo is a structure used for storage of bulk materials, in which the loads due to stored materials has to be taken into account in addition to wind load and seismic load. The various codes and standards stipulate guidelines for the silo design. The four codes studied and compared in this paper viz., a) Indian Standard IS 4995 – 1974 b) American Concrete Institute ACI 313 – 97 c) German Standard DIN 1055 – 6: 2005 –03 and d) British Standard BS EN 1991-4: 2006. Though, theanalysis and design of silo cannot be performed using single code, the lack of compatibility among various codes makes the designers difficult in designing the silo. The consideration of minor modifications in the analysis and design of silo makes it possible to construct and operate safe and economical silo. The aim of this paper is to compare and briefly describe about the superiority and limitations of four codes.
