Seismic Analysis and Design of RCC Silo by Considering Different Seismic Zones and Soil Types

Abstract

Tanks, silos, bunkers, and bins are examples
of buildings used to store bulk solids. There is
no standard term for these structures;
towering buildings used to store commodities
like coal, wheat, and cement are called silos,
while shallow buildings used to store coal,
gravel, crushed stone, and other items are
named bins or bunkers. It is possible to lift
and sustain elevated silos with reinforced
concrete frames or columns. Typically, they
feature a cylindrical shell, a conical hopper,
and a conical roof. Many businesses, such as
the cement, power, and oil and gas sectors
(where sulfur pellets are stored) and cement
plants (which store clinkers), use circular silos
made of steel or reinforced concrete to store
materials. Elevated steel and reinforced
concrete circular silos for storage
demonstrate how they perform during
earthquakes; the stability of the reinforced
concrete silos is increased by the use of shear
walls, while the stability of the steel silos is
increased by the use of steel panels on the
opposite side. Shear wall panels cause the
structure to move less and become stiffer. The
load calculations, load combinations, load
assignment, seismic parameters, and analysis
have all been documented in this study, and
the analysis's findings have also been
provided and compared. All of the model
outputs are shown, along with the minimum
values needed for beams and columns. The
maximum absolute stresses and maximum
shear stresses created in each model are
shown by contour diagrams, tables, and
graphs.
