SIMULATION OF WOOD BURNING PROCESS BY FINITE ELEMENT METHOD

Abstract

The concept of laboratory or field research is increasingly being replaced by computer simulations. It is already common for every engineer to simulate the static and dynamic operation of a structure using the finite element method. Another question arises in the simulation of emergency effects such as fire. If for materials which possess ability to keep the geometrical characteristics for a long time the decision is realized, then for such material as wood for which during a fire burnout and variable section is characteristic, realization of simulation of such settlement situation by means of a method of final elements is a difficult enough task. This article presents the results of modeling and calculation of the loaded wooden column by the finite element method, as well as theoretical calculations of the column in case of one-sided local damage of the section as a result of fire. The aim of the work is to compare the results of calculations by the theoretical method of DSTU-N-P B V.2.6-157: 2010 with the results obtained by the finite element method. Calculation of a design by a method of finite elements are realised in software complex Lira. The calculation is done in a flat production. The results of calculation are obtained and conclusions about expediency of using the finite element method for calculation of tasks, for which reduction of construction cross-section in time is characteristic.
