Project funded by Research Council of Lithuania 2014-2016 m.
Researcher teams project „Effective reinforcement for increased stiffness and cracking resistance of concrete structures“, funded by Research Council of Lithuania. The project runs from 2013-03-03 to 2016-12-31 and is implemented by the department of Bridges and Special structures of Vilnius Gediminas Technical University (VGTU). Project Manager – Viktor Gribniak, researchers – Gintaris Kaklauskas, Adas Meškėnas, Arvydas Rimkus, Vytautas Tamulėnas, Vaidotas Gelažius. Unlike the general practice of the engineering researchers (when mechanical behaviour of building structures and materials are analysed separately), current project aims at development of the effective reinforcement schemes, simultaneously investigating two main aspects: 1) structural (ability of the cracked concrete to resist tensile stresses and variation of this parameter in the real constructions); and 2) technological (production possibility and costs). Optimal selection of the structural materials and combination of their mechanical properties will lead to the reduced variation of the mechanical properties of the real structures and, thus increase reliability of the design (the numerical simulation results).
