3D reconstruction of existing concrete bridges using optical methods
Popescu, Cosmin; Täljsten, Björn; Blanksvärd, Thomas; Elfgren, Lennart (Peer reviewed; Journal article, 2019)Routine bridge inspections usually consist of visual observations. These inspections are time-consuming and subjective. There is a need to identify new inspection techniques for infrastructure that reduce traffic disturbance, ... -
A comparison between laser, scanning, photogrammetry and infrared scanning to create 3D digital models of existing concrete bridges
Popescu, Cosmin; Täljsten, Björn; Blanksvärd, Thomas; Elfgren, Lennart (Chapter, 2020)Routine bridge inspections usually consist of visual observations. These inspections are time-consuming and subjective. There is a need to identify new inspection techniques for infrastructure that reduce traffic disturbance, ... -
Axially Loaded RC Walls with Cutout Openings Strengthened with FRCM Composites
Sabau, Cristian; Popescu, Cosmin; Sas, Gabriel; Blanksvärd, Thomas; Täljsten, Björn (Journal article; Peer reviewed, 2018)Abstract: Upgrading existing buildings to new functional requirements may require new openings that can weaken the structure, prompting the need for strengthening. In such cases traditional strengthening solutions, such ... -
Concrete walls with cutout openings strengthened by FRP confinement
Popescu, Cosmin; Sas, Gabriel; Blanksvärd, Thomas; Täljsten, Björn (Peer reviewed; Journal article, 2017)Redesigning buildings to improve their space efficiency and allow changes in use is often essential during their service lives to comply with shifts in living standards and functional demands. This may require the introduction ... -
Finite element analysis of shear deformation in reinforced concrete shear-critical beams
Huang, Zheng; Lü, Zhitao; Tu, Yongming; Blanksvärd, Thomas; Sas, Gabriel; Elfgren, Lennart (Journal article; Peer reviewed, 2017)The objective of this paper was to study the contribution of shear deformation in reinforced concrete (RC) shear-critical beams. A 2D concrete material model based on smeared fixed crack was presented and incorporated into ... -
Local and global behavior of walls with cut-out openings in multi-story reinforced concrete buildings
Sabau, Cristian; Popescu, Cosmin; Bagge, Niklas; Sas, Gabriel; Blanksvärd, Thomas; Täljsten, Björn (Journal article; Peer reviewed, 2019)This paper presents the finite element analysis (FEA) results of a multi-story reinforced concrete (RC) building having precast and cast-in-place load bearing walls. Door-type cut-out openings (height: 2.1 m, width: 0.9–4.4 ... -
Performance of RC Walls with Openings Strengthened by Fiber Reinforced Polymers: An Experimental and Theoretical Investigation
Popescu, Cosmin; Sas, Gabriel; Blanksvärd, Thomas; Täljsten, Björn (Chapter, 2017)Redesigning buildings to improve their space efficiency and allow changes in use is often essential during their service lives to comply with shifts in living standards and functional demands. This may require the introduction ... -
Review of FRCM strengthening solutions for structural wall panels
Sabau, Cristian; Popescu, Cosmin; Sas, Gabriel; Blanksvärd, Thomas; Täljsten, Björn (Chapter, 2018)This paper summarizes the state-of-the-art on the topic of structural wall panels strengthened using fabric reinforced cementitious matrix composites (FRCM) composites. A systematic review of the literature is carried out ... -
Strengthening of RC beams using bottom and side NSM reinforcement
Sabau, Cristian; Popescu, Cosmin; Sas, Gabriel; Schmidt, Jacob Wittrup; Blanksvärd, Thomas; Täljsten, Björn (Journal article; Peer reviewed, 2018) -
Workflow for Off-Site Bridge Inspection Using Automatic Damage Detection-Case Study of the Pahtajokk Bridge
Mirzazade, Ali; Popescu, Cosmin; Blanksvärd, Thomas; Täljsten, Björn (Peer reviewed; Journal article, 2021)For the inspection of structures, particularly bridges, it is becoming common to replace humans with autonomous systems that use unmanned aerial vehicles (UAV). In this paper, a framework for autonomous bridge inspection ...
