• Static load test on concrete pile – instrumentation and results interpretation

  Publikacja

  • A. Krasiński
  • M. Wiszniewski

  - Rok 2017

  For some time (since 8-10 years in Poland) a special static load tests on instrumented piles are carried out. Such studies are usually of a scientific nature and provide detailed quantitative data on the load transfer into the ground and characteristics of particular soil layers interaction with a pile shaft and pile base. Deep knowledge about the pile-subsoil interaction can be applied for a various design purposes, e.g. numerical...

• Identification of residual force in static load tests on instrumented screw displacement piles

  Publikacja

  • A. Krasiński
  • M. Wiszniewski

  - Studia Geotechnica et Mechanica - Rok 2021

  Occurrence of the so-called residual force of an unknown value significantly disturbs interpretation of static load tests performed on piles equipped with additional measuring instruments. Screw displacement piles are the piling technology in which the residual force phenomenon is very common. Its formation mechanism is closely related to the installation method of this type of piles, which initiates generation of negative pile...

• Bearing capacity of piles based on static load tests and calculation principles provided by EN 1997-1

  Publikacja

  • K. Gwizdała
  • A. Krasiński
  • T. Brzozowski

  - Rok 2011

  W artykule scharakteryzowano i przeanalizowano ogólne zalecenia Eurokodu 7 dotyczące wyznaczania nośności pali na podstawie próbnych obciążeń statycznych. Porównano je z zaleceniami dotychczasowej polskiej normy PN-83/B-02482. Przedstawiono kilka przykładów interpretacji rzeczywistych wyników próbnych obciążeń pali według zaleceń wyżej wymienionych dwóch norm wraz z analizą porównawczą.

• Screw displacement pile shaft deformations measured by vibrating wire and fiber optic systems during a static load test

  Publikacja

  • M. Wiszniewski
  • A. Krasiński

  - Rok 2022

  This paper describes a full scale static load test performed on a 400 mm diameter screw displacement pile equipped with four different strain measuring systems. Three types of vibrating wire strain gauges (VWSG) were used: global - retrievable, local attached to steel pipe and local concrete embedded. The fourth system was distributed fiber optic sensors based on Rayleigh back scattering (DFOS) - three in the pile cross section....

• Load capacity of steel-aluminium brackets under static and cyclic laboratory tests

  Publikacja

  • A. Ambroziak

  - Archives of Civil Engineering - Rok 2021

  The aim of the research is the laboratory investigation of steel-aluminium brackets employed to fasten lightweight curtain walls to building facilities. Static pressure, suction forces, and cyclic loads parallel to end plates (horizontal – to simulate wind influence) were applied in the study. The steel-aluminium brackets were tested on a reinforced concrete substrate made of C30/37 concrete class to simulate the real working conditions....

• Morphology of damage inflicted on brittle polymer in lubricated contact under cyclic static load

  Publikacja

  • T. Stolarski
  • P. Vongbandit

  - TRIBOLOGY LETTERS - Rok 2011

  In this article morphology of damage inflicted on the polymethylmethacrylate (PMMA) plate in static point lubricated contact with a ball made of five different materials under cyclic normal load has been presented. It is argued that the counterface material and lubricating film play an important role in the damage process and the extent of damage inflicted in the PMMA plate.

• Application of probabilistic tools to extend load test design of bridges prior to opening

  Publikacja

  • P. Owerko
  • K. Winkelmann
  • J. Górski

  - Structure and Infrastructure Engineering - Rok 2020

  Load tests of bridges are widely performed in a large number of countries. Deterministic comparison of measurement results to the theoretical, FEM (finite element method)-based outcomes with possible further calibration is mostly applied. Sometimes, the data collected in the tests are also used to calibrate the reliability factors of bridge structures or their components. This work proposes to complement the stage of the load test...

• Corrugated Sheeting as a Member of a Shear Panel Under Repeated Load—Experimental Test

  Publikacja

  • N. Korcz-Konkol
  • P. Iwicki

  - Materials - Rok 2020

  In stressed-skin design, the cladding stiffening effect on structures is taken into account. However, the “traditional” design is more usual, wherein this effect is neglected. Even if the diaphragm actions are not regarded, in particular cases such as big sheds (and others), the parasitic (unwanted) stressed-skin action may occur with the result of leakage or even failure. The structures of this kind have already been built. Thus,...
