NONLINEAR BEHAVIOUR OF CYLINDRICAL WALL OF GROUND ELEVATED EMPTY RC SILO UNDER WIND LOAD

Nonlinear analysis of civil structures gives as an analyst’s tool and entered the practicalworld of design engineering. Most FEA applications undertaken by design engineers were limited to linear analysis.It has been demonstrated that the ultimate strengths of some typical two-story planar frames (under gravity loads) determined by inelastic analysis are 10–30% higher than those estimated from the first-hinge elastic approach. Design of silos using the nonlinear analysis has described in this thesis. In  this  thesis  it  has  shown  that  nonlinear  analysis  of  two models  i.e.,  Model  2.3  and  Model  2.4  the  dimension  of  that  silos  are  height  6.4&12.8m respectively. Analysis has done on that silo by incorporating the nonlinear properties to those models as M25 grade concrete properties and changing step module values.It has explained that how the stresses vary in case of nonlinear analysis.
