INVESTIGATION AND EVALUATION OF THERMAL ANALYSIS FOR DIFFERENT WALL STRUCTURES WITH FINITE ELEMENT METHOD, SIMULATION OF TEMPERATURE DISTRIBUTION AND REACTION IN THE WALL TYPES

Abstract

When the literature is examined it is figured out that crack/stress occurrence and temperature change in walls are closely related. Therefore, the study of the thermal reaction of the temperature changes in the wall structures is beneficial to understand and to acquire information on the crack /stress behavior and dynamic changes in the wall and the surroundings. It is considered that information and gained knowledge on the subject can lead to developing a methodology for checking building structure security and for detecting a body under debris. The calculation methods for the temperature field distribution of the concrete structures are investigated in this study. This is done by applying the Finite Element (FE) numerical model for the computation of the wall heat flux and thermal distribution under the reaction of a step temperature change at a wall side with given default and barrier conditions. The temperature variations due to the change in the structure of the wall are examined. Thermal properties and crack/stress, expansion situations are visualized, simulated, and analysed for typical walls by displaying temperature distribution and heat flow with the specified baseline and barrier conditions. This study presents a multi-aspect thermal analysis method that can allow the researchers to compare the thermal response of typical walls under different ambient conditions by showing simulated results for typical walls. Thermal stress analysis on the wall types should be performed to arrange a ground to reduce and control the existence of thermal cracking. The results of the study will be considered an asset to support further studies and investigations.
