Question:
Answer:Set the member type of the element for design.
In the program, if elements are parallel to the Z axis, they are set as columns. And if elements are parallel to the X-Y plane, they are set as beams by default. In the model file, the superstructure is bent, so it is recommended to modify the member type of elements as 'Beam'. Here are the steps to modify member type.
1. Select [Design > Common Para. > Modify Member type].

2. Select elements for which you want to change the memeber type.
