变电工程钢筋混凝土防火墙温度作用分析

Analysis of Thermal Effect of Reinforced Concrete Firewall in Substation Engineering

变电工程中户外防火墙常采用现浇钢筋混凝土墙结构,气温变化及太阳辐射等因素产生的温度作用往往不可忽视。针对某换流站内现浇钢筋混凝土防火墙,运用有限元分析软件ANSYS建立三维实体模型以进行温度作用效应计算,分析墙体温度变形及温度应力的特点,为墙体抗裂设计提供参考。

Outdoor firewalls in substation projects often adopt cast-in-place reinforced concrete wall structures,and the temperature effects caused by factors such as temperature changes and solar radiation cannot be ignored.Aiming at the cast-in-situ reinforced concrete firewall in a converter station,the finite element analysis software ANSYS is used to establish a three-dimensional solid model to calculate the temperature effect,the characteristics of the wall temperature deformation and temperature stress are analyzed,and the reference for the wall anti-cracking design is provided.
