A comparative study of beam element formulations for nonlinear analysis: corotatinal vs. geometrically exact formulations
(Chapter, 2017)In this work the geometrically exact three-dimensional beam theory has been used as basis for development of a family of isoparametric higher order large deformation curved beam elements. Geometrically exact three-dimensional ... -
A framework for estimating the implicit safety level of existing design codes
(Chapter, 2017)Target safety levels ( t ) are key elements for reliability-based design and calibration of design codes. They are derived by monetary optimization or from existing codes. The current article discusses these two approaches ... -
Aerodynamic Effect of Non-uniform Wind Profiles for Long-Span Bridges
(Chapter, 2019)Long-span bridges are often designed based on the assumption of wind field homogeneity. At the Hardanger Bridge, the wind field along the bridge span is monitored though 8 triaxial ultrasonic anemometers. Simultaneously ... -
Alkali Aggregate Reactions (AAR) in concrete. The Norwegian endeavour during more than 3 decades of research
(Chapter, 2022)It is now more than 80 years since Alkali Aggregate Reactions (AAR) first were reported as a deleterious deterioration mechanism in concrete. In Norway, AAR was recognised in the late nineteeneighties. Norwegian experience ... -
Aluminium plates with pre-formed slits subjected to blast loading
(Chapter, 2018)The dynamic response of thin, perforated aluminium plates subjected to blast loading was studied both experimentally and numerically. Two different blast intensities were used and the plates were pre-cut with four horizontal ... -
Aspects of fluid-structure interaction on the dynamic response of blast-loaded metallic plates
(Chapter, 2019)This work presents results from an experimental and numerical investigation on the influence of fluid-structure interaction (FSI) on the dynamic response of thin steel plates subjected to blast loading. The loading was ... -
Ballistic perforation resistance of plain and reinforced concrete slabs - An experimental and numerical study
(Chapter, 2023)As concrete is the most used construction material globally, it is vital to understand how this complex composite material behaves when subjected to extreme and potentially devastating loads like explosions or ballistic ... -
Blast load performance of concrete slabs after ballistic impact from ogive-nose projectiles
(Chapter, 2023)Concrete is by far the most used construction material in the world and is frequently used in critical infrastructure and protective structures. Whether intentional or accidental, ballistic impact and blast loading pose ... -
Blast loading of concrete pipes using spherical centrically placed C-4 charges
(Chapter, 2018)The Norwegian Public Roads Administration has initiated a large research project on a potential ferry-free coastal highway route E39 from Trondheim to Kristiansand. Parts of this route involve crossing somewide and deep ... -
Blast-load response of thin steel plates after ballistic impact from small-arms projectiles
(Chapter, 2019)This paper investigates the dynamic response of 0.8 mm thick steel plates exposed to a combination of ballistic impact and blast loading. Two different materials, i.e., a medium-strength (Docol 600DL) steel and a high-strength ... -
Bolted RHS end-plate joints in axial tension
(Chapter, 2012)An experimental study is carried out for end-plate joints for rectangular hollow sections (RHS) in axial tension. Two designs of the plate are considered; one with bolts on two opposite sides of the RHS, and one with bolts ... -
Brittleness of High-Strength Lightweight Aggregate Concrete
(Chapter, 2018)Modern society and infrastructure are facing an increased demand for fast construction. A number of viaducts are aged and will need to be replaced in near future. When considering this replacement task, lightweight, slender ... -
Challenges related to structural modelling and assessment of concrete structures affected by alkali-silica reactions
(Chapter, 2017)Alkali-Silica Reaction (ASR) in concrete is a chemical process between dissolved alkali and hydroxyl ions from pore solutions in the cement paste, and reactive (amorphous) silica within the aggregates. The product of the ... -
Classification boundaries for stiffness of beam-column joints and column bases
(Chapter, 2012)Eurocode 3 part 1-8 gives stiffness boundaries for nominally pinned, semi-rigid and rigid beam-to-column joints and for semi-rigid and rigid column bases. The background for these limits has been investigated and analysed ... -
Code-to-Code Verification of End-Anchored Floating Bridge Global Analysis
(Chapter, 2018)A code-to-code comparison of the dynamic characteristics of an end-anchored floating pontoon bridge is presented for two commercial software commonly used in the offshore industry, i.e. SIMO-RIFLEX and ORCAFLEX. Furthermore, ... -
Concrete ice abrasion: Deterioration mechanisms, testing and modeling
(Chapter, 2012) -
CONCRETE-ICE ABRASION: SURFACE ROUGHNESS AND MEASUREMENT METHOD
(Chapter, 2015)The wearing of concrete material due to ice movement is a cutting edge problem for offshore and coastal engineering. The phenomenon is often referred to as concrete-ice abrasion, but the physics of this process is not ... -
Coupled fluid-solid modelling of the valve dynamics in reciprocating compressors
(Chapter, 2022)A novel method coupling computational fluid dynamics (CFD) and finite element method (FEM) was developed to account for the complex physics of the reciprocating compressor. The developed method is based on data exchange ... -
Crash behavior of obliquely loaded aluminum extrusions
(Chapter, 2002)The energy absorbing capability of obliquely loaded aluminum extrusions was studied through quasi-static experiments. Square aluminum columns in alloy AA6060 were clamped at one end and oblique load conditions were realized ...
