To develop a durability plan for a girder bridge with a design life of $100$ years?

Available on Canvas in Module "Bridge design project $-$ Spring $2024"$:

$"42907$ Design Project $-$ Bridge general details"

$"42907$ Design Project $-$ Bridge design tasks"

$"42907$ Design Project $-$ Preliminary detailings", providing a set of preliminary design drawings of the girder bridge reinforced$/$prestressed concrete members, comprising:

Reinforced concrete footings

Reinforced concrete columns

Reinforced concrete headstock beams

Reinforced concrete top$-$slab $($bridge deck$)$

Reinforced concrete barriers on bridge deck $($precast$)$

$"42907$ Design Project $-$ Design methods" a durability plan for a girder bridge with a design life of $100$ years.

Mandatory concrete specifications for your project:

Minimum $28$ days characteristic compressive strength is $50$ MPa of all structural members.

Only GGBFS is available for this project as Supplementary Cementitious Material.

In general, to reduce the concrete embodied carbon, always use the maximum allowed GGBFS content in the binder composition in accordance with AS$5100\mathrm{.}5$ specifications. However, due to some limitations in GGBFS supply for this project, the maximum GGBFS content allowed is $50\%$
