   Sammanfattning : The use of inclined piles is an efficient way to handle horizontal forces in constructions. However, if the soil settles the structural bearing capacity of each pile is reduced because of induced bending moments in the pile. There are several reasons for a soil to settle, e.g. LÄS MER

3. 2. Optimization of Pile Groups : A practical study using Genetic Algorithm and Direct Search with four different objective functions

   Master-uppsats, KTH/Bro- och stålbyggnad

   Författare :Ann Bengtlars; Erik Väljamets; [2014]
   Nyckelord :Pile Group Optimization; objective function; Genetic Algorithm; Direct Search; Pattern Search; Pålgruppsoptimering; målfunktioner; Genetic Algorithm; Direct Search; Pattern Search;

   Sammanfattning : Piling is expensive but often necessary when building large structures, for example bridges. Some pile types, such as steel core piles, are very costly and it is therefore of great interest to keep the number piles in a pile group to a minimum. LÄS MER
