Arano Barenys, Assis (author), Colombo, Matteo (author), Martinelli, Paolo (author), Øverli, Jan Arve (author), Hendriks, M.A.N. (author), Kanstad, Terje (author), di Prisco, Marco (author)This study investigated the effect of fire on the ultimate load-bearing capacity of reinforced concrete (RC) slabs. The structural response of RC circular specimens subjected to static load conditions after exposure to a hydrocarbon fire on one side of the specimen was examined. Two fire exposure times were considered (60 and 120 min) in...journal article 2022

Arano, Assis (author), Colombo, Matteo (author), Martinelli, Paolo (author), Øverli, Jan Arve (author), Hendriks, M.A.N. (author), Kanstad, Terje (author), Di Prisco, Marco (author)Advanced numerical modeling of high-strength concrete (fc>60 MPa) structures designed to withstand severe thermal conditions requires detailed and reliable information on the mechanical properties of the material exposed to elevated temperatures. The only uniaxial compressive strength variation with temperature is not enough to satisfy the...journal article 2021

Colombo, Matteo (author), Martinelli, Paolo (author), Arano, Assis (author), Øverli, Jan Arve (author), Hendriks, M.A.N. (author), Kanstad, Terje (author), di Prisco, Marco (author)Reinforced concrete (RC) submerged floating tunnels (SFTs) represent a possible solution for crossing wide, deep fjords, and is considered for the E39 highway route along the Norwegian west coast. With regard to SFTs, the specific accidental scenario that is under investigation is the combined action of fire and subsequent internal explosion,...journal article 2021

Zivkovic, Jelena (author), Lukovic, M. (author), Øverli, Jan Arve (author), Hordijk, D.A. (author)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 bridge is the solution. Dead load reduction and high-strength to weight ratio are the main advantages when using the...conference paper 2018

Non-linear finite element analyses applicable for the design of large reinforced concrete structuresEngen, M (author), Hendriks, M.A.N. (author), Øverli, Jan Arve (author), Åldstedt, Erik (author)In order to make non-linear finite element analyses applicable during assessments of the ultimate load capacity or the structural reliability of large reinforced concrete structures, there is need for an efficient solution strategy with a low modelling uncertainty. A solution strategy comprises choices regarding force equilibrium, kinematic...journal article 2017

Engen, Morten (author), Hendriks, M.A.N. (author), Øverli, Jan Arve (author), Åldstedt, Erik (author)A fully triaxial material model for concrete was implemented in a commercial finite element code. The only required input parameter was the cylinder compressive strength. The material model was suitable for non-linear finite element analyses of large concrete structures. The importance of including a crack closure algorithm was demonstrated on a...conference paper 2016

Peacock, R.E. (author), Øverli, J. (author)Recent developments in pressiire sensing and trajisfer techniques have made possible the detailed investigation of the aerodynamic behaviour of rotor blades. Tests on a lightly loaded single stage compressor using this instrianentation have yielded pressure distributions at rotor blade hub, mid-height and tip sections and give new evidence on...report 1973
