Part 2: Design for durability

The objective is the design for durability of three structural members of a girder Bridge according to AS5100.5. Design for durability will include specification of concrete (concrete characteristic compressive strength and mix design) and concrete cover for the three structural reinforced concrete members to satisfy the 100 years service life. The three reinforced concrete members to be designed for durability are:

1- Foundations: reinforced concrete footings

2- Bridge piers: reinforced concrete columns

3- Bridge deck: reinforced concrete top-slab
