某支架结构温度作用研究

Study on temperature action in support structure system

根据空冷凝汽器支架结构温度荷载的特点,设计了三种温度计算工况,采用SAP2000程序计算了空冷支架结构温度效应,给出了结构构件内力变化范围及规律。为了协调温度与地震作用的矛盾,提出了三种设计对策,从而减少结构及其上部设备的破坏。

According to the characteristics of different temperature actions, three calculating temperature cases are designed. SAP2000 code is used to calculate the temperature effects of the support structure system of air cooled condenser, and then the scope and distribution of internal force or stress of each kind component are provided. In order to harmonize the contradiction caused by temperature and earthquake action, three designing methods are suggested, so the destroy of the structure and equipments can be reduced when the structure is subjected to earthquake.
