  • Experimental tests of lintel hybrid beams

    Publikacja

    - Rok 2019

    The results of experimental tests of lintel hybrid beams made of air concrete and prestressed concrete were presented in paper. Blocks of air concrete was a protective element for the construction one. The length of hybrid beams was 3.0 m, while total height 27 cm. It was assumed that hybrid beams will work in the simply-supported scheme (with a 10 cm support) loaded uniformly over the entire length. The object of the tests were...

  • Experimental tests of reinforced concrete deep-beams

    Publikacja

    - Rok 2014

    The paper presents results of experimental research of the reinforced concrete deep beam with a spatial arrangement. Tested structural elements consist of the cantilever deep beam loaded on the height and transverse deep beam with hanging on it another one. The analysis includes crack morphology, effort of steel and load distribution. The article verified effectiveness of two different kind of reinforcement in both tested deep...

  • Experimental tests of water lubricated marine rubber bearing

    Publikacja

    - Rok 2008

    W referacie przedstawiono stosowane obecnie rodzaje łożysk gumowych smarowanych wodą. Omówiono ich zalety i wady.W drugiej części pracy przedstawiono wyniki badań eksperymantalnych typowego okrętowego łożyska gumowego. Uzyskane rezultaty porównano z wynikami badań łożysk z polimerową panwią.

  • Experimental tests of steel double-type balcony connections

    Publikacja

    - Czasopismo Techniczne - Rok 2024

    The paper presents analysis and results of experimental tests of full scale prefabricated balcony sets with dimensions (width × length × height): 2.0 m × 2.78 m × 0.186 m (in slope to 0.17 m). The sets consists of reinforced concrete slabs (balcony and ceiling) connected with each other by double-type balcony connections. The paper analyses the impact of variable parameters on the load carry capacity of elements. Additionally...

  • Truss models of RC corbels verified by experimental tests

    Publikacja

    - Rok 2005

    W pracy przedstawiono wybrane modele kartownicowe krótkich wsporników żelbetowych oraz obliczone na podstawie tych modeli nośności graniczne wsporników na tle wyników uzyskanych w badaniach eksperymentalnych. Przedstawiono także weryfikację metody ścinania-tarcia wg wytycznych normy amerykańskiej. Dokonano obliczeń częściowych współczynników bezpieczeństwa, uwzględniających niepewność rozważanych modeli. Stwierdzono, ze modele...

  • Experimental tests for the determination of mechanical properties of PVC foil

    Publikacja

    - Rok 2016

    The paper presents an application of the PVC film in civil engineering. Mechanical behaviour of the PVC film applied for suspended ceilings, in the form of a stretch ceiling is investigated under uniaxial and biaxial tensile tests. The study is focused on the determination of mechanical properties from experimental data (uniaxial and biaxial tensile tests). The uniaxial cyclic tests are performed in order to observe a variation...

  • FEM ANALYSIS AND EXPERIMENTAL TESTS OF RIGID RISER HANGING SYSTEM

    Publikacja

    - Polish Maritime Research - Rok 2018

    The article presents the analysis, project, and experimental examination of an original rigid riser for Coil Tubing Pipes. The principle of riser operation is based on the use of friction forces. The research included the FEM analysis of the designed riser, calculations of the required bolt tensions, and checking the effect of the clamping force on stress distribution in the pipeline. The results of computer simulation were verified...

  • Generalization of Phylogenetic Matching Metrics with Experimental Tests of Practical Advantages

    Publikacja

    - JOURNAL OF COMPUTATIONAL BIOLOGY - Rok 2023

    The ability to quantify a dissimilarity of different phylogenetic trees is required in various types of phylogenetic studies, for example, such metrics are used to assess the quality of phylogeny construction methods and to define optimization criteria in supertree building algorithms. In this article, starting from the already described concept of matching metrics, we define three new metrics for rooted phylogenetic trees. One...

  • Dynamic tests of composite footbridge segment – experimental and numerical studies

    Publikacja

    - MATEC Web of Conferences - Rok 2019

    Experimental dynamic tests and numerical simulations of a 3 meters long segment of a footbridge made of polymer composites are presented in the paper. The span-length is reduced, however dimensions of cross-section are the same as the target footbridge. The segment structure is made of sandwich panels, which consist of fibre reinforced polymer (GFRP) laminates (skins) and a PET foam (core). The first part of the paper contains...
