Concrete Column Design

Question $6$

Using the concrete column design methodology from your lectures $($located in 'Structural Elements Design Manual, Working With Eurocodes'$)$ calculate and select the realistic size and location of the required longitudinal reinforcement for the following reinforced concrete columns: $($Column $1$ and Column $2)$

$($all calculations and sections through must be shown. Print$-$outs from design$-$packages will not satisfy the Learning Outcome$)$

Column $1$

A braced rectangular column $300mm400mm$ in C$30$ concrete carries at ULS an axial load of $1000kN$ and a maximum bending moment of $195kNm($in the direction of the $400mm$ dimension.

The column has an effective length of $2215mm($and is NOT slender$)$

Determine the longitudinal reinforcement required $($main bars $H25$ with $H8$ ties and cover of $30mm)$

Column $2$

A braced rectangular column $400mm550mm$ in C$30$ concrete carries at ULS an axial load of $1250kN$ and a maximum bending moment of $255kNm($in the direction of the $550mm$ dimension.

The column has an effective length of $2350mm($and is NOT slender$)$

Determine the longitudinal reinforcement required $($main bars $H32$ with $H8$ ties and cover of $30mm)$
