| 摘 要： | 应用MSC．Marc软件对某发电厂干煤棚网架结构建立了空间网格结构的有限元模型。基于该模型和干煤棚的实际工作状态，研究火电厂干煤棚网架在风载荷、雪载荷、温度等各种正常工况下的变形规律，总结出干煤棚网架在各种工况下的变形规律，与网架异常时的变形相比较，为干煤棚在线监测系统的开发提供理论依据。

| Abstract: | MSC.Marc was employed in static analysis and modal analysis of a large grid structure for a coal storage in a power plant. The deformation behavior of the coal shed under some circumstances like wind load,snow load and temperature were discussed based on this model and the real running states. The reliable principle was provided to develop the monitoring system for online coal shed. |
