Rigid Zone Factors and Panel Zone

[mortezamobariz]

hello every one

i have a question for you in steel design. 

Subject: Steel Connection

when should we use rigid zone factor and when should we use joint spring and when should we use panel zone?

Typically the Rigid End Zone (REZ)factor of 0 would assume a centerline based model which is typical of most basic analysis and should be accurate enough in general practice.  

Using a REZ of 1.0 assumes there are zero deformations within the area at the intersection of the columns and beams known as the "Panel Zone" (it is infinitely rigid).  The "true" case lies somewhere in between and could be modeled using a rotational spring layouts (e.g. a scissors or krawinkler model). 

These factors and definitions are software dependent. Please see the software manual for more details.
