Concrete Chimney Stress Analysis System Based on Finite Element Analysis

Abstract

The invention discloses a finite element analysis based concrete chimney stress analysis system. The finite element analysis based concrete chimney stress analysis system comprises an input module, a calculation module, a conversion module, an ANSYS calling module and an SAP2000 calling module. The input module is used for inputting basic parameters of a chimney. The calculation module is used for calling the basic parameters to calculate auxiliary parameters required in modeling the chimney. The conversion module is used for calling the basic parameters and the auxiliary parameters and converting the parameters into a command stream file supported by ANSYS software. The ANSYS calling module is used for leading the command stream file into ANSYS to generate an ANSYS model with cell attributes. The SAP2000 calling module is used for leading the ANSYS model into the SAP2000 and analyzing stress through input analog load. The finite element analysis based concrete chimney stress analysis system is reasonable in structure and convenient to use, modeling process of the chimney is simplified, input and calculating amount of the parameters of designers is lowered, and analyzing efficiency is improved.

Description

technical field [0001] The invention relates to a stress analysis system of a concrete chimney, in particular to a system for realizing the stress analysis of a concrete chimney by a computer. Background technique [0002] Finite element analysis is a method that uses mathematical approximation to simulate real physical systems, divides a complex physical system into a finite number of simple and interacting units, and obtains the overall approximate solution of the physical system by solving each unit Analytical method. This method can be used to analyze very complex structures, so it has been widely valued by people as soon as it appeared, and soon developed into a very important engineering calculation method, and has been widely used in engineering design and research. [0003] As an important structural building, chimney occupies a relatively important position in national industry. In some large-scale thermal power plants, steel companies, chemical plants and other p...
