Abstract
This report contains a study of the structural loading capacity for driven concrete piles in cohesive soil. Two different types of models for handling horizontal loads have been investigated. The most common way in Sweden to cope with horizontal loads on piles is to drive the piles inclined in a truss pattern. The pile head is then thought to be
hinged and the horizontal load is transmitted to the soil by normal force in the pile. In this model the lateral resistance of the soil is used only to stabilize the pile against buckling. If the pile head is made as a rigid joint the lateral resistance of the soil can be used to support the horizontal load. The piles can then be driven vertically.

The analysis is made by hand calculating... (More)
This report contains a study of the structural loading capacity for driven concrete piles in cohesive soil. Two different types of models for handling horizontal loads have been investigated.

If the pile head is made as a rigid joint the lateral resistance of the soil can be used to support the horizontal load. The piles can then be driven vertically.

The analysis is made by hand calculating methods and the design standard used is
Eurocode.

For comparison a pile group analysis was carried out for the two above given methods to cope with horizontal load on piles. The result indicates that the truss pattern model with hinged joints has greater horizontal load capacity when normal forces are significant which is the case when dealing with heavy structures. For vertically driven piles with rigid joints the result indicates that they are more advantageous when vertical forces are moderate, i.e. light structures. (Less)
