Abstract

The seismic behavior analysis of a reinforced concrete cooling tower using SAP2000 aims to simulate and evaluate the structure’s response to seismic loads, both from near and far movements. This process begins with the creation of a numerical model that incorporates the tower’s geometry, construction materials, and anticipated seismic loads and constraints. The cooling tower is supported by I-type and Ʌ-type columns. Relevant comparisons of the dynamic response of the structural system have been made at the base level (where the columns meet the shell), throat level, and at the top of the tower. The results from these analyses enhance our understanding of the cooling tower’s seismic behavior, highlighting areas of excessive stress, potential deformations, and components vulnerable to damage during an earthquake. This information is vital for informing structural improvements that enhance the seismic resistance of the cooling tower and ensure its stability during seismic events, regardless of their proximity.

考虑不同支柱支撑系统的双曲线冷却塔在地震作用下的动态响应

使用 SAP2000 对钢筋混凝土冷却塔进行地震行为分析的目的是模拟和评估结构对来自近距离和远距离运动的地震荷载的响应。分析过程首先是创建一个数值模型，将冷却塔的几何形状、建筑材料、预期地震荷载和约束条件纳入其中。冷却塔由 I 型柱和Ʌ 型柱支撑。对结构系统的动态响应进行了相关的比较，包括塔基（支柱与外壳的交接处）、喉管层和塔顶。这些分析结果加深了我们对冷却塔地震行为的理解，突出了应力过大的区域、潜在的变形以及在地震中容易损坏的部件。这些信息对于改进结构，提高冷却塔的抗震能力，确保其在地震发生时的稳定性（无论距离多近）至关重要。
