it a concrete encased steel composite column. It consists of a steel UC (universal column), with 8 additional steel longitudinal reinforcement bars  which is then encased in concrete.  Dimensions of the UC – obtain from Liberty Steel hot-rolled section properties product guide Spacing is the distance from the edge of the UC to the centre of the reinforcing bar Cover is the distance from the edge of the concrete to the centre of the reinforcing bar:Material properties are Esteel = 200 GPa Econcrete = 28 GPa, and both materials experience linearly elastic behaviour. The member is used as a column and is subjected to axial compression. UC type : 200UC52.2 steel bar diameter ds(mm): 16 spacing: 2.5 ds cover :70mm column height (L/duc):24 fsteel,max = 95MPa fconcrete,max= 12MPa strain (concrete)max = 425 x 10^-6 max shortening =2.25 mm  the column must satisfy the various stress, strain and absolute shortening limits  What is the maximum axial load P to satisfy all the design criteria? Your answer should clearly show the values of steel and concrete stress and strain, and axial shortening, for this value of P. The engineer decides to move the location of the steel reinforcing bars by slightly increasing the spacing dimensions, with a corresponding decrease in the cover dimensions. The overall concrete dimensions do not change. How will that impact the sharing of load between the steel and concrete compared to the original?
