description: The topic of the final qualifying work: "the Effect of the barrel roll on the stress-strain state of a reinforced concrete chimney h=180 meters". The work is devoted to determining the effect of possible barrel rolls on the stress-strain state (VAT) of the chimney h=180 meters.
The purpose of the study - is to determine the influence of the size of possible barrel rolls on the characteristics of the stress-strain state of a reinforced concrete chimney.
The object of research - is a reinforced concrete chimney with a height of h=180m.
The subject of research is - the construction, vertical deviations, forces and deformations of the chimney trunk.
Tasks to be solved in the research process:
1. Review of literature sources for the analysis of structural solutions of industrial reinforced concrete chimneys and foreign construction.
2. Study of normative documents and methods for calculating reinforced concrete chimneys for power and temperature effects.
3. Development of a computational finite element model of an industrial reinforced concrete chimney h=180 meters in the environment of the LIRA-CAD 2016 computing complex.
4. Determination of the influence of barrel roll values on the stress-strain state of an industrial reinforced concrete chimney.
5. Development of recommendations for determining the permissible limits for safe operation of barrel rolls on the example of a reinforced concrete chimney h=180m.
The design model of the chimney trunk was reproduced according to the standard project â 907-2-92 of a reinforced concrete chimney h=180 m for industrial enterprises. The main parameters of the chimney for the calculation were: geometric characteristics of the annular sections, the height of the pipe, the diameter of the exit hole, the location of viewing platforms on the height of the pipe and the working conditions of the trunk. The calculations were performed using the LIRA-CAD-2016 software package. The LIRA-CAD software package is based on the finite element method. This software package is well-tested in relation to the construction structures of buildings and structures. To determine the stress-strain state of the chimney, the main and special types of impacts (loads) were collected and applied to the trunk structures. The calculated data were obtained on the characteristics of the stress-strain state of the pipe stem elements under the most unfavorable combinations of loads and impacts.
The influence of the barrel roll values on the characteristics of the stress-strain state of a reinforced concrete chimney, as one of the most important objects of mass industrial construction, is determined. Based on the results of calculations, recommendations were developed for determining the permissible limits of barrel rolls for safe operation on the example of a chimney h=180m.
