For example, in a pier bent with 10 vertical piles and 2 batter piles, the batter piles will take probably 90...- sfamularo

HELP NEEDED ON HARBOUR DESIGN
All of the questions asked are very broad in their scope. I will do my best to answer each on some level... 1. Almost everything needs to be taken into account when designing a new harbor! Global Scale - defining the purpose of the facility...is it for local fisherman, for a specific...- sfamularo
