烟气脱硝作为当前大气污染治理的重要内容正逐步成熟与发展，但其钢结构支架形式复杂多样。本文依托热电厂工程实际，对两种脱硝钢结构分别施加静力和地震两种荷载作用进行数值模拟，研究了两种结构的受力和结构水平位移及沉降。通过对两种结构时程加载结果的分析，验证了弹塑性设计和结构阻尼比的对结构设计的重要意义。

At present, SCR fume denitrification system is improving and developing as a significant way to combat air polution, but the steel structures used for it are complex and varied. This paper based on a practical project of power plant studies in stress and horizontal displacement of the two structures by static and seismic numerical simulation. According to the result of time history analysis, the importance of elastic-plastic design and structural damping ratio is presented.
