摘　　要：针对现阶段结构分析中广泛采用的等效荷载处理方法的不足,提出采用非等效荷载处理方法处理结构上的各种荷载。基于梁板结构有限元分析中常用三节点平面壳单元,采用面积坐标处理单元上作用的常用荷载,编制了相应的有限元分析程序。算例结果比较分析表明该方法实用、可行。非等效荷载处理方法简单直观、易于理解应用,能够帮助有限元软件开发人员提高工作效率。To overcome the shortcomings of the traditional equivalent load processing method in structural analysis,a non-equivalent load processing method in finite analysis of slab-beam structures was suggested and realized through program.In the processing method loads on elements were treated in area coordinates based on three-node shell elements.Verification was conducted by comparison and analysis of a numerical example.It was showed that the non-equivalent load processing method is easy and convenient for application and helpful to promote the work efficiency.
