1.	Cyron, Wojciech, et al. (author) Bonded Concrete Overlays: A Brief Discussion on Restrained Shrinkage Deformations and Their Prediction Models 2019 In: Nordic Concrete Research. - : Walter de Gruyter. - 0800-6377 .- 2545-2819. ; 61:2, s. 107-129 Journal article (peer-reviewed)abstract Bonded concrete overlays (BCO) on bridge decks are beneficial solutions due to their superior properties as compared to the typical asphalt pavement. A significant number of overlays suffer however, from occurrence of cracks and delamination due to poor bond, and restrained shrinkage and thermal dilation. Over the past years different appraisals for estimation of the restrained deformations have been developed, from micro-scale models, based on poromechanics, to empirical equations as given in B3 or B4 models suggested by Baiant. This paper provides a short overview of calculation models along with a brief theoretical explanation of shrinkage mechanism.
2.	Nilsson, Martin, et al. (author) Fastenings (anchor bolts) in concrete structures : influence of surface reinforcement 2012 In: Concrete Structures for Sustainable Community. - Stockholm : Swedish Concrete Association. - 9789198009811 ; , s. 419-422 Conference paper (peer-reviewed)abstract Tests have been carried out to study the influence of surface reinforcement on the load bearing capacity of cast-in headed bars. In 66 tests, rods with a diameter of Φ30 mm and a Φ45 mm nut at the end, were cast-in place centrically in concrete slabs. Width, length and thickness of the slabs varied from 1.2 m × 1.2 m × 0.3 m up to 2.2 m × 2.2 m × 0.6 m. The top reinforcement varied from 0% to about 1.2% (Φ 16 #100). A considerable increase in the load-bearing capacity was noted. The increase depends on the geometry and the amount and placement of the reinforcement. A numerical model to evaluate the influence is proposed.
