Hi there. I would like to ask things about the subject please bear with me.
1.) I noticed that in the STAAD file Member Cracked Property(beam), reduction factors were used with values of 0.5 for Moment of Inertia and 1.0 for Cross Sectional Area and 1.0 for Torsion Constant, kindly someone explain or point to any references why and when we need to use this member specification and what will be the effect or the importance of using this? (same goes with the columns specification)
2.) I also noticed that nodes 2, 49 and 73 were treated as Rigid Master Nodes, again why and when and what will be the effect or the importance of using this node specification?
Thank you in advance...
