Continue Reading...structures pile groups are used and usually subject to lateral loading. Group interaction effects are very important and impressive in piles behaviour under lateral loading. Computer simulations of finite element modeling allow for in- depth studies into the complex pile–soil–pile interaction under lateral loading in deep foundation ...
