About Development and Verification of Software for Finite Element Analysis of Beam Systems

AbstractThe distinctive paper is devoted to author's software (Windows application) for finite element analysis (FEA) of beam systems. Program application package provides convenient graphical interface to the user for quick creation of layout design in accordance with given coordinates of nodes. User can specify various boundary conditions in the corresponding nodes or apply external loads. The results of FEA are displayed in text and graphical forms (including visualization of deformed scheme). Moreover, these results can be exported into a Microsoft Word document. Open source and freeware program has been created by Microsoft Visual C++. Information about verification samples is presentedClic

The Organization of Autodesk Revit Software Interaction with Applications for Structural Analysis

AbstractThe article deals with the export procedure of building construction parameters from Autodesk Revit to the program of structural analysis. At first, the procedure uses the C# plug-in, which extracts parameters of the construction elements from the Revit document and outputs them to a text file. The parameters can be physical (properties of materials), geometrical (size, coordinates, the cross-sectional shape) and other. Then, a special program-converter reads the file, generates a beam frame model and stores the information in a new format, which is compatible with the program of structural analysis earlier developed by the authors. This program allows to add both vertical or horizontal loads and moment to any of the beam frame nodes. The finite element method is used for structural analysis. The deformation schema is showed as the result of finite element analysis under the loads. The opportunity to get Microsoft Word document, which contains main characteristics of beam construction, is implemented

RESEARCH OF BEHAVIOR OF CEMENT COMPOSITES IN CONDITIONS OF HIGH HUMIDITY AND VARIABLE POSITIVE TEMPERATURES

In this paper, the results of testing cement composites under the conditions of the effect of high humidity and variable positive temperatures are given.By the coefficient of variation of hardness (stability), the compositions are compared with various fillers, plasticizing and other fungicidal additives.To decide on the stability (stability) of the structure and properties of composites, it is proposed to rely on the area of the polygon obtained as a result of piecewise linear approximation of the exposure points. Explanations of the influence of environmental factors on hardness change of the composites
