用ansys如何计算三层框架正弦激励后的位移响应?

我是菜鸟;用ansys建了一个三层框架的模型;
命令流如下:

想在结构上加sin13t的正弦激励,然后得到某一单元的位移响应信号,请问该如何做呢?
求高手告知,我将不胜感激!!时间间隔可以取0.01s;时程为20s。
非常感谢!

那些无用的旋转,放大的操作,
楼主可否考虑在命令流里给删除..
那样读起来会简便点..

抱歉,我是新手

不好意思,我是菜鸟,刚刚接触的ansys;
是照着书上的算例做出来的框架模型,然后把命令流导出来了;
谁能帮帮俺如何加荷载呢?多谢各位了!

怎么没人回复俺呢?

大家看看有没有人可以帮帮俺的?谢谢了!
