A new set of design aids for groups of four cylindrical silos due to interstice and internal loadings

摘要: The computation of design forces for reinforced concrete groups four cylindrical silos requires significant computational effort due to continuity in the walls between adjacent silos. This paper presents a simple but accurate procedure acting on stored materials. In this conjunction, finite element analyses were performed by using eight-node solid elements various under interstice and internal loadings. at prescribed sections external computed. silo wall thicknesses, intersection thicknesses lengths these grouped varied with an extensive parametric study demonstrate their influences resultant forces. Design formulas proposed dimensionless coefficients derived from comprehensive series considering effect walls. results expressed simplified form, so that prediction bending moments, axial shear became straightforward purposes. addition, rigidity was changing modulus elasticity redistribution investigated.
