CoreBrace buckling restrained brace shapes are now available in the RAM Structural System. This feature allows the engineer to conveniently assign CoreBrace shapes to buckling restrained braces in the RAM model.
To model, analyze and design buckling restrained braces using CoreBrace shapes, do the following:
Select the CoreBrace Master Steel Table A Master Steel table, COREBRACEAISC.TAB, is now available containing the CoreBrace brace shapes. This table is a duplicate of the RAMAISC.TAB table that contains all of the AISC shapes for beams, columns and braces, with the addition of the CoreBrace shapes. To select this Master Steel table select the Criteria - Master Steel Table command and select COREBRACEAISC from the list of tables. Note that this table can be edited and updated if necessary as explained in the RAM Manager manual.
Create the model, including braces Create the model in the Modeler. Typically Fy for the braces is specified a value in the range of 38 to 46 ksi. CoreBrace can assist the engineer in determining the appropriate value to use.
Assign sizes to the braces Brace sizes can be assigned either with the Layout - Braces - Assign Size command in Elevation View in the Modeler or with the Assign - Braces - Size command in RAM Frame.
The CoreBrace shapes are listed under the Flat Bar shapes. Select the desired size from the list and assign it to the braces in the model.
In the 3D View CoreBraces are drawn as square braces, scaled to the size of the typical casing for that brace size. Contact CoreBrace for the exact size of the casing for the actual geometry.
