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
