  Dyskutowana jest synteza i właściwości magnetyczne tlenku niobu Nb12O29. Polimorfizm Nb12O29 przejawia się występowaniem dwóch faz: jednoskośnej i ortorombowej. Pomiar podatności magnetycznej pokazuje, że faza jednoskośna wykazuje antyferromagnetyczne przejście ok. 12K.

• Sensitivity analysis of critical loads of I-columns

  Publikacja

  • P. Iwicki

  - Archives of Civil Engineering - Rok 2007

  The first order variation of critical buckling load of thin-walled columns with bisymmetric open cross-section due to some variations of the design variables such as: cross-section dimensions, or material characteristics is derived. The influence of the residual welding stresses is taken into account. In the numerical examples dealing with I-column the functions describing the effect of the variation of the dimensions of the flange...

• Sensitivity analysis of flexural and torsional buckling loads of laminated columns

  Publikacja

  • M. Kujawa
  • C. K. Szymczak

  - AIP Conference Proceedings - Rok 2019

  The paper concerns first order sensitivity analysis of flexural and torsional bucklin g loads of axiallycompressed thin-walled columns with bisymmetric or axisymmetric cross-section made of unidirectional fibre-reinforcedlaminate. The first variation of critical loads versus some variations of the column material properties and cross-sectionaldimensions is derived. Numerical examples dealing with simply supported I-columns are...

• Incorporating installation effects into the probability analysis of controlled modulus columns

  Publikacja

  • J. Konkol

  - SOILS AND FOUNDATIONS - Rok 2023

  This technical report presents the probabilistic analysis which integrates the Monte Carlo simulation (MCS) with random field theory to model the load–displacement behavior of Controlled Modulus Columns (CMCs) in overconsolidated Poznań clay. Presented study focuses on the practical aspects of statistical analysis of geotechnical data, numerical model development, and results evaluation. Variability and spatial distribution of...

• Numerical analysis on axial capacity of steel built-up battened columns

  Publikacja

  • P. Pieczka
  • P. Iwicki

  - Archives of Civil Engineering - Rok 2022

  This paper deals with the numerical analysis aimed at study the bearing capacity of pinended steel built-up columns under axial compression. Finite element (FE) models were performed for the columns presented in the literature. The main problem discussed in the article is the shape and magnitude of geometric imperfections introduced into the numerical FE model, necessary to obtain the load capacity consistent with the experimental...

• Simplified stability analysis of steel cylindrical silos with corrugated walls and vertical columns

  Publikacja

  • K. Rejowski
  • P. Iwicki

  - Rok 2016

  In the paper a simplified stability analysis of steel cylindrical silos composed of corru¬gated walls and vertical open-sectional columns was proposed. The whole 3D silo was modeled as a single column resting on elastic foundation provided by the silo walls. In proposed formula for the calculation of the foundation stiffness the curvature of the silo walls was taken into account. Three different analyses were carried out using...

• Behaviour of deformed steel columns exposed to impact load during earthquakes: numerical analysis

  Publikacja

  • W. Migda
  • R. Jankowski

  - Journal of Applied Sciences - Rok 2012

  It has been observed during earthquakes that the so called soft-storey failure of an upper floor of a building leads to considerable vertical impact load acting on structural members of the lower storeys. The aim of this paper is to investigate numerically the behaviour of horizontally deformed columns (deformation as the result of earthquake loading) that are additionally subjected to vertical impact load. In the first stage of...

• Investigation of buckling resistance of columns using non-linear static and dynamic analysis

  Publikacja

  • Ł. Żmuda-Trzebiatowski
  • P. Iwicki

  - Rok 2014

  The aim of this paper is to investigate the stability process in an axially compressed column using a static and dynamic finite element analysis by taking both the geometric and material non-linearity into account. The perfect column and column with geometric imperfections were analysed. The linear buckling analyses were used to obtain the lowest buckling load and shapes of buckled forms that were taken into account as initial...
