Ultimate Limit State Design of Spread Foundations in The Case of Uplift
(13th Baltic Sea region geotechnical conference. Historical experience and challenges of geotechnical problems in Baltic Sea region, 2016, 2016)As vast majority of spread foundations are never subjected to vertical uplift loads, the subject of uplift capacity in such cases is barely covered by current European standards. Although the limit state design due to ... -
Numerical Modelling of Inclined Piles in Settling Soil
(13th Baltic Sea region geotechnical conference. Historical experience and challenges of geotechnical problems in Baltic Sea region, 2016, 2016)The allowable load for slender end-bearing piles in soft soils driven or drilled to compact till or rock frequently depends on the structural capacity of the pile. Pile groups consisting of such slender preceast concrete ... -

Ice Loads on Structures in the Baltic Environment
(13th Baltic Sea region geotechnical conference. Historical experience and challenges of geotechnical problems in Baltic Sea region, 2016, 2016)For offshore, nearshore and harbour structures ice loading is often a decisive ULS load. However, the Code requirements, the regulations and design practices vary considerably across the Baltic Sea region and beyond. This ... -
Usage of Wood Fly Ash in Stabilization of Unbound Pavement Layers and Soils
(13th Baltic Sea region geotechnical conference. Historical experience and challenges of geotechnical problems in Baltic Sea region, 2016, 2016)Modification and stabilization of road structure unbound layers has extensively been studied both at laboratory and field for decades. The most commonly used binders for soil modification and stabilization are cement and ... -
