There are two options:

 

1). Use forces in points (see the attached picture)

2). Use panels instead of claddings - check this topic http://forums.autodesk.com/t5/Autodesk-Robot-Structural/Wooden-frames-in-Robot-structural-analysis-a... and focus on the message 4

Thank Artur.Kosakowski

I is Know.

 

Please toturial guide me

1)how to find  Centre of mass point coordinates ( XYZ)

2) how to find  centre of rigidity point coordinates (XYZ)

Thank you.

1. Ask ETABS

2. Do not compare slab resuls and story results.

Thansk

but I can not find centre of mass.

I just saw center of gravity and center right. But i don't see center of mass.

Please help me.

centre of mass = centre of gravity

thanks tony.

Your comments help me to define such a right?

1. center of geometry =  F - Coordinates of the center of gravity of story slab

2. center of mass = G - Coordinates of the center of gravity of story

3. center of rigidity = R - Coordinates of the center of rigidity of the section at the height of the story's center of gravity, considering the columns,walls and core walls.

Please. THansk
