摘要
一阶弹性分析中,钢框架稳定计算的核心问题就是计算长度的确定.火力发电厂中,很多钢结构由于工艺的需求,都是不规则的框架结构形式,计算长度的确定是比较困难的,对于不规则的钢框架的计算长度,当根据规范难以确定时,计算长度应通过弹性稳定分析获得.可采用理论分析法或计算机求解法进行结构的弹性稳定计算,其中计算机求解法方便快捷,且计算结果精确可靠,应大力进行推广.
The calculation length of steel column is the core issue for stability calculation of steel frame structure;while use the first order elastic analysis.There are many irregular steel structure in the thermal power plant due to the needs of the process major.It is difficult to get the calculation length of irregular frame columns;when it is difficult to get the calculation length according to the specification schedule,the calculation length should be obtained by elastic stability analysis.The elastic stability analysis of structures can be carried out by theoretical analysis or computer analysis;among them,the computer solution method is convenient and quick;and the calculation results are accurate and reliable.It is necessary to popularize and apply computer to analyze the elastic stability of structures.
