“…A TRC egy olyan kompozit anyag, mely nagyon széles körben alkalmazható, akár szerkezeti rehabilitációknál [3][4][5][6][7], könnyű teherhordó szerkezetekhez [8,9], vagy homlokzati lemezekhez [10][11][12][13][14]. A TRC elemek geometriájától függően többféle formázási módszert alkalmaznak: zsaluzást, szórást vagy laminálást [15].…”

The textile reinforced concrete is a material with increased mechanical properties that can allow the production of lighter structural elements. The alkali-resistant textile reinforcement is not affected by corrosion. A structural facade panel and a light pole were modelled in order to study their behavior in case of wind pressure. The developed numerical simulations were calibrated upon the available data from the literature. These simulations revealed some information that may worth to be taken into consideration in order to plan further experimental tests.

“…Subject to investigations up till now have been only the parameters of a stack of wooden elements used for elimination of defl ections of low structures, with up to three stories (Gromysz, 2018). Moreover, the analyses of axially and eccentrically loaded elements have been carried out mainly in relation to reinforced concrete elements (Kabir & Shafei, 2012), steel columns (Nie, Kang, Shen & Yang, 2017) and masonry structures (Bernat--Maso, Gil & Roca, 2015;Moradabadi, Laefer, Clarke & Lourenço, 2015). Respectively, the results of the experimental research concerns mainly glass fi bre reinforced polymer-reinforced geopolymer concrete -GFRP-RGC (Elchalakani, Karrech, Dong, Ali & Yang, 2018), steel (Nie et al, 2017), masonry structures (Cavaleri, Failla, Mendola & Papia, 2005;Bernat-Maso, Gil & Escrig, 2015) and composite multi-drum columns (Buzov, Radnić, Grgić & Baloević, 2018).…”

The removal of building deflections consists of uneven raising of buildings with piston hydraulic jacks. A stack of parallelepiped steel elements is situated under jacks during defl ection removal for technological reasons. The stack has decisive influence on the stiffness of the supports. Tests of the stack of parallelepiped elements loaded with increasing and decreasing force were designed and carried out. Three characteristic phases were identified based on the tests. The maximum stiffness in particular phases was, respectively 13.1, 63.1 and 10.1% of theoretical stiffness.

“…A straightening process has to be interrupted several times as a result, temporary supports have to be dismounted and walls have to be constructed for the part of the building remaining in the ground. The analyzes of eccentrically loaded elements have been carried out mainly in relation to reinforced concrete elements [5], steel columns [6] and masonry structures [7,8]. Respectively, the results of the experimental research concern mainly GFRP Reinforced Geopolymer Concrete [9], steel [6] and masonry structures [10][11][12].…”

Temporary supports consisting of a jack, a stack of wooden cubic elements and a iron plate are used during the removal of buildings deflections by uneven raising. Where the weight of a building is rested on temporary supports with a considerable length, unintentional displacements of buildings in the horizontal direction are seen. The displacements are connected with supports deformations caused by horizontal forces acting on the building part being raised. Non-vertically installed jacks, being part of the supports, are the most frequent reason for the occurrence of such forces. The jacks are not vertical due to deformations in the stack of wooden elements, upon which they are rested. In such case, the stiffness of temporary supports is essential for the safety of the deflection removal process. Laboratory tests of temporary supports were carried out and they showed that their stiffness, understood as a horizontal force divided by a displacement in the acting direction of the force, is not constant. The stiffness of supports is decreasing as the displacement amplitude grows. A considerable decrease in supports stiffness was experienced when positive longitudinal deformations occurred in the cross section of the support elements. As a result, the unconnected elements of the supports were unable to transmit positive stresses of this number. For the investigated range of loads, the deformations of the material of the supports elements were elastic. Inelastic forces were however generated along the contact points of the elements forming part of the supports, and such forces were responsible for creating a hysteresis loop and energy dissipation by the supports. The system, when a full load-unload cycle was applied, was returning to the initial position. Higher values of the energy dissipation coefficient correspond to higher values of a displacement amplitude.
