1. Shear in Concrete Structural Elements Subjected to Dynamic Loads
Sammanfattning : Concrete structural elements subjected to severe dynamic loads such as explosions at close range may cause shear failures. In the Oklahoma City bombing in 1995 two concrete columns on the ground level were reported to have failed in shear. LÄS MER
2. Quality aspects in direct shear testing of rock joints
Sammanfattning : The stability of rock masses is influenced by the occurrence of rock joints. Therefore, the shear strength of rock joints must be considered in dimensioning of underground constructions. LÄS MER
3. Mechanical Behavior of Tailings : Laboratory Tests from a Swedish Tailings Dam
Sammanfattning : Tailings is leftover material from mining industry and is produced in huge quantities approximately 70-99% of the ore production. Tailings material is stored as impoundments by constructing tailings dams which are often constructed with tailings material itself. LÄS MER
4. Estimating the Air-Water Gas Transfer Velocity during Low Wind Conditions
Sammanfattning : The abundances of atmospheric carbon dioxide, CO2, and methane, CH4, are increasing. These increases affect e.g., the global carbon cycle and the climate both regionally and globally. LÄS MER
5. Undrained shear strength in clay slopes - Influence of stress conditions. A model and field test study
Sammanfattning : To counteract natural hazards such as landslides, current methods for evaluation of soil properties as a mean for determining the safety level of natural slopes need to be refined. The empirical relationships used for estimation of the undrained shear strength from piezocone and field vane test are based on the stress conditions valid for horizontal ground and normally consolidated or slightly overconsolidated soil.
