How to scale down a model in Sap2000?

How to scale down a model in Sap2000?

(OP)
Recently, I've been working on a concrete structure using Sap2000, the geometry of the structure was kind of hard, which I had to spend alot of time on it. Although I finished the analysis and design a few weeks ago, the architect changed the model by scaling down the whole model and reducing the dimensions to 70% of the original model.  Now I want to know if there is a way to make the whole model smaller without regenerating the geometry.

Thanks alot

It used to be easier in earlier versions where an SF=0.7 entry could be entered into the .S2K file. Now that entry is gone.

The idea is simple. Modify only the coordinate entries: X=, Y= , and if necessary Z=.

There are two ways you can do that.

1)Export an S2K file,manually edit the coordinates, save the S2K and then import the S2K file in SAP2000 blank screen. You can use the Replace option of the textprocessor you use(eg notepad or wordpad). Remember s2K is a text file

2)Open the existing model, choose Edit-Interactive Database Editing from the pull down - choose Joint Coordinates from the resulting screen and you will have an IDE(Interactive Database editing) screen with coordinates shown in tables. You can edit each coordinate, choose Done when you are done, and save changes to model. Here too you can use the Replace option to speed up text changes.

Hope this helps
