Abstract

The stability and durability of concrete materials are essential factors in the construction industry. Environmental conditions, such as  temperature affect the tensile strength and durability of concrete structures. This work investigates the thermodynamic behaviour of  hollow cylindrical concrete using the finite element method (FEM). By deploying ANSYS®, the element mesh was created, and the  temperature distribution inside the hollow cylinder was calculated. The effect of the hollowness of the concrete on its heat absorption is  determined. The findings demonstrate that the temperature profiles changed radially throughout the concrete thickness. Moreover, it  was discovered that the temperature distribution was impacted by the airflow into the cylinder. The numerical experiment in this study  was essential in providing a comprehensive understanding of the behaviour of the concrete, particularly when exposed to higher heating  rates. This study contributes to the knowledge of the performance and stability of concrete materials. It also demonstrates that the  hollowness of the concrete enhances its heat-shielding performance. Furthermore, the inflow of air into the cylinder affects the  temperature distribution, with a higher influx of air resulting in lower temperatures. These findings can be utilised to develop appropriate  measures to enhance the performance and durability of concrete structures. 
空心混凝土圆柱体热力学响应的数值分析
混凝土材料的稳定性和耐久性是建筑业的基本要素。温度等环境条件会影响混凝土结构的抗拉强度和耐久性。本研究采用有限元法(FEM)研究了空心圆柱混凝土的热力学行为。通过部署 ANSYS®,创建了元素网格,并计算了空心圆柱体内部的温度分布。确定了混凝土空心程度对其吸热的影响。研究结果表明,在整个混凝土厚度范围内,温度分布呈径向变化。此外,还发现温度分布受到进入圆筒的气流的影响。本研究中的数值实验对于全面了解混凝土的行为,尤其是暴露于较高加热速率时的行为至关重要。这项研究有助于了解混凝土材料的性能和稳定性。研究还表明,混凝土的空心率提高了其热屏蔽性能。此外,空气流入气缸会影响温度分布,空气流入量越大,温度越低。这些发现可用于制定适当的措施,以提高混凝土结构的性能和耐久性。
