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, ... -
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 ... -
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 ... -
