Fragility Assessment of Transportation Infrastructure Systems Subjected to Earthquakes
(Chapter, 2018)This paper provides a review of the different methodologies for the fragility assessment of critical transportation infrastructure subjected to earthquake excitations with emphasis placed on geotechnical effects. Available ... -
Freezing induced stresses in concrete-steel composite beams and effect of air voids
(Chapter, 2016)The thermal expansion match between concrete and steel is lost when freezing occurs, owing to enhanced shrinkage caused by cryosuction in the pore solution and the high coefficient of thermal expansion (CTE) of ice. Freezing ... -
Frost dilation measurements on concrete cores from a dam with ASR
(Chapter, 2008)In order to evaluate length change measurements to determine damage in concrete due to both ASR and internal frost attack, concrete cores drilled from a 25 year old dam with slight ASR and some surface frost damage were ... -
FROST TESTING NON-AIR ENTRAINED SUPPLEMENTARY CEMENTITIOUS MATERIALS HIGH PERFORMANCE CONCRETE: SALT-SCALING AND INTERNAL DAMAGE
(Chapter, 2023)Air-entrainment is difficult with high volumes of Supplementary Cementitious Materials (SCM). High Performance Concrete (HPC) with low w/b without air-entrainment can, however, survive severe deicer salt frost performance ... -
Frost testing of HP/HVFA concrete for severe offshore conditions
(Chapter, 2019)In the Durable Advanced Concrete Solution (DACS) project lead by Kvaerner and supported by a group of Norwegian concrete industries and The Norwegian Research Council the production and documentation of frost durable ... -
Fundamental study on ASR kinetics - effect of temperature on aggregate reactivity and pore-water composition
(The International Conference on Alkali-Aggregate Reaction (ICAAR);Theme 4, Chapter, 2021) -
Global Buckling Reliability Analysis of Slender Network Arch Bridges: An Application of Monte Carlo-Based Estimation by Optimized Fitting
(Chapter, 2017)Network arch bridges are extremely slender bridge structures with a very efficient 16 load-carrying structure. This configuration can carry loads that are several times greater 17 than traditional tied-arch bridges with ... -
Ice abrasion testing of high performance concrete for offshore structures
(Chapter, 2019)Offshore concrete structures exposed to drifting sea ice have abrasion of the concrete surface caused by the mechanical contact between ice and concrete in the order of 0.1 to 1 mm per year. The concrete-ice abrasion ... -
Ice abrasion testing of HP concrete for offshore structures
(Chapter, 2019)Offshore structures can be exposed to drifting sea ice. The wear (abrasion) of the concrete surface caused by the mechanical contact between ice and concrete is in the order of 0.1–1 mm per year. The concrete-ice abrasion ... -
Impact behavior of high-strength steel at low temperatures
(Chapter, 2018)A wide range of material and ballistic tests were conducted to explore the behavior of a high-strength steel at low temperatures. Our test program included quasi-static and dynamic uniaxial and notched tension tests, Charpy ... -
Impact of Hydrodynamic Interaction Between Pontoons on Global Responses of a Long Floating Bridge Under Wind Waves
(Chapter, 2018)The hydrodynamic interaction between floating bridge pontoons and its impact on the bridge global responses are investigated in the current study. The global model for end-anchored floating bridge for Bjørnefjord crossing ... -
Impact of super absorbent polymers on early age behavior of high performance concrete walls
(Chapter, 2021)The prediction of the early age behavior of cementitious materials is a difficult task, because many of the material properties are very sensitive to curing conditions as it is the case for High Performance Concrete (HPC), ... -
Influence of brittle fracture on the crashworthiness of ship and offshore structures in Arctic conditions
(Chapter, 2016)Structures operated in Arctic regions are exposed to low temperatures, which may be in the range of the ductile- brittle transition temperature (DBTT) of steel. This implies that the brittleness of the material in such ... -
Inverse identification of buffeting and self-excited wind loads on the {Hardanger} bridge from acceleration data
(Chapter, 2019)The traditional wind load assessment for long-span bridges rely on assumed models for the wind field and aerodynamic coefficients from wind tunnel tests, which usually introduces some uncertainties. It is therefore desired ... -
Investigation of the products of the dolomite reaction in Portland cement pastes
(Chapter; Peer reviewed, 2017)The formation of potentially deleterious reaction products from the reaction of dolomite fines in Portland cement pastes was investigated. It was shown that the reaction of dolomite fines did not follow the commonly accepted ... -
Investigations on the feasibility of the CWE method to verify potential alkali release from aggregates in Norwegian field concrete
(Chapter, 2021)Concrete elements exposed for 26 years to seawater spray and deicing salts along a road close to Sandnessjøen in Norway were investigated. Concrete cores from 4 elements with different binder compositions (A: 100 % Portland ... -
Long-term extreme response analysis of marine structures using inverse SORM
(Chapter; Peer reviewed, 2017)In this paper the first order reliability method (FORM) found in connection with structural reliability analysis is first used in an inverse manner to efficiently obtain an approximate solution of the full long-term extreme ... -
Material characterization and modeling of textured aluminum alloys used in a bumper system
(Chapter, 2005)In the present paper, two materials AA7108 and AA6060, which can be parts of a typical bumper system in aluminum, have been characterized. Material properties were identified for a material model that was recently implemented ... -
