rodzaj: materiały konferencyjne w książce
Abstrakt: The article compared the transmission of underground vibrations caused by mines to foundations of representative low-rise masonry buildings situated in two different seismically active mining areas in Poland: the Legnica-Glogow Copperfield (LGC) and the Upper Silesian Coalfield (USC). The soil-structure interaction (SSI) effect has been investigated on experimental measurements of free-field (near to the building) and building foundation vibration accelerations occurring at the same time. Long-term (several years, hundreds of strong shocks), full-scale monitoring with the application of so-called ‘an armed partition’ measuring equipment, was carried out. The focus has been on the horizontal vibrations in the directions of the transverse and longitudinal axis of the buildings. It has been stated that records of the ground and building foundation vibrations registered at the same time can vary considerably in the case of the LGC, as well as the USC mining regions. The differences between the ground and building foundation vibrations have been analysed using the comparisons of dimensional and dimensionless response spectra from the building foundation and free-field vibrations, respectively. Furthermore, the relationship between the foundation and ground response spectra, the so-called ratio of response spectra (RRS), has been taken into account. Influences of epicentre distance, the magnitude of mining tremor energy, peak ground value of vibrations related to mining tremors on the SSI in the case of the same type of building but situated in mining regions with some differences concerning, e.g., site conditions, have also been analysed and compared.]]>

<![CDATA[Bond behaviour of seven-wire non-pretensioned plain strands embedded in high-performance concrete]]> Fri, 02 Dec 2022 10:50:35 +0100 Seruga, Andrzej
rodzaj: materiały konferencyjne w książce
Abstrakt: The bond of prestressing strands can vary with regard to the size of strand, the type of concrete mixture, the age and strength of concrete and many other factors. The bond level is significant for composite action between the concrete and steel, especially in the transfer zone of the pretensioned member. Tensioning force release can usually be performed when obtaining a minimal concrete compressive strength at the level of 40 MPa. Such a strength is required for a concrete maturity of twenty-four hours or less, which is not easy. With help comes the application of modern high-performance concrete (HPC) technology. A research program to examine the bond of HPC on the concrete composition grade of C80/95 was designed. The concrete specimens with untensioned 7ɸ4 mm (12,9 mm dia.), 7ɸ5 mm (15,7 mm dia.) and 7ɸ6 mm (18,2 mm dia.) strands were precast in individual moulds. Six strandembedment lengths were tested: 40, 80, 120, 240, 330 and 460 mm. The main tests concerned measurements of slip between the strand and the concrete surface and were made with using an electronic extensometer attached to the free end of strand and concrete surface. The bond stressslip curves and bond strength versus free-end slip relationship was analysed. All specimens were tested in the laboratory of the Institute of Materials and Building Structures of Cracow University of Technology, Cracow, Poland.]]>

Abstrakt: Selected Papers from the V th Modern Power Systems and Units Conference in Celebration of Professor Jan Taler on His 70 th Birthday Wiesław Zima and Piotr Cisek Department of Energy, Faculty of Environmental and Power Engineering, Cracow University of Technology, Cracow, Poland The International Scientific and Technical Conference – “Modern Power Systems and Units” (MPSU) has been organized by the Department of Energy, Cracow University of Technology, for over 15 years. The MPSU conference is a periodic event organized in Cracow, Poland, every three years, starting from 2007. The Vth International Scientific and Technical Conference “Modern Power Systems and Units” 2021 was held on May 19-21, 2021. Because of the COVID19 restrictions, the conference was held entirely online. Within the conference, five international plenary sessions and eighteen working sessions were held, where the latest achievements in the field of power technologies were presented. In total, 162 papers were presented, including 15 plenary keynote speeches, 72 full presentations, and 75 short presentations. The total number of participants present at the conference was over 200 people. The MPSU 2021 conference was unique, especially for the Polish scientific community. The entire ceremony was held in honor of Professor Jan Taler, one of the most outstanding Polish scientists in power engineering, who was celebrating his 70 th birthday.]]>

Abstrakt: By definition, a smart, sustainable city is technologically enabled, connected and agile to address economic, environmental and social challenges. The success of a smart city, however, also relies on the competencies of its citizens, suggesting a re-modelling of engineering education towards a learner-centred, competency-based education. This paper gives an overview of the challenges encountered throughout implementing the BIOART multinational curriculum development project. A project that tackled the challenges for an inclusive, resilient smart city concept by developing novel teaching and learning content and adopting innovative educational methodologies in biomedical engineering, a.o. in the context of an internationally organised summer school and online hackathon.]]>

Abstrakt: Cooperation of an university and a private company resulted in developing of composite skeleton made of spruce wood of C24 class and polymer flexible adhesive, being innovative solution investigated during a project in Poland. Structural elements were constructed using flexible adhesive layers made of special two component polyurethanes of 3 mm thickness and installed in prototype timber houses. Carried out research on this innovative solution indicated that flexible bonding of wood can be applied in civil engineering practice. Following this idea, new research was carried out at Cracow University of Technology in Poland focusing on parametric analysis of flexible bonding using in structural connection of Douglas Fir wood (Pseudotsuga Carriere) and flexible polyurethane Sika PS. Tested specimens were constructed in form of beams with three various flexible adhesive thicknesses of 1 mm, 2 mm and 4 mm. The beam specimens were tested in bending under elevated temperatures of 20, 40, 60 and 80 Celsius degrees, resulting in load capacity and deflection measurements. Nonlinear behavior of tested flexible adhesives provided advantageous stress concentration reduction and even stress redistribution along the bond-line. Basing on the obtained results, various specimens numerical modeling of the innovative system. Finite Element Method numerical models were calibrated using experimental results and analysis allowed to visualize phenomenon of structural flexibility, which manifested promising properties in behavior of structural elements made of wood and flexible adhesives. Carried out research is aimed on developing of new wood-adhesive technology, more advantageous than classical systems using stiff and very thin layers of adhesives.]]>
<![CDATA[Procedury uwzględniania wpływu drgań komunikacyjnych na budynki eksploatowane]]> Wed, 23 Nov 2022 13:57:07 +0100 Kawecki, Janusz; Tatara, Tadeusz

Abstrakt: Opracowanie nawiązuje do ogólnych wymagań zapisanych w Prawie ochrony środowiska dotyczących oceny standardów jakości środowiska odnoszących się do emisji drgań pochodzących od eksploatowanych dróg. Podano tu procedury przydatne w ocenianiu wpływu na budynki eksploatowane drgań generowanych przejazdami pojazdów w pobliżu tych budynków. Drgania takie są wymuszeniem kinematycznym budynku i mogą doprowadzać do jego uszkodzeń (rysy, uszkodzenia elementów architektonicznych, zarysowania w elementach konstrukcyjnych itp.). Z kolei drgania w budynku mogą wpływać na naruszenie warunków niezbędnego komfortu wibracyjnego. Mogą też naruszać wymagania odnoszące się do warunków pracy urządzeń wrażliwych na drgania w budynkach eksploatowanych. Zadaniem rzeczoznawcy jest opracowanie diagnozy, w wyniku której uzyskuje się informacje o tym, czy istnieje związek skutkowo-przyczynowy między naruszeniem warunków bezpiecznej eksploatacji budynku a działaniem źródła drgań. Zastosowanie procedur tu opisanych powinno ułatwić wykonanie takich diagnoz. Postępując według podanych procedur rzeczoznawca będzie stosował odpowiednie narzędzia diagnostyczne, o których niezbędne informacje również zamieszczono w niniejszym opracowaniu.]]>
