Hi I am using the rigid diaphragm through the use of Penalty Functions and Lagrange Multipliers for a static pushover analysis of a 3D building with plane (with element infrmFB) and I have different results. what is the right kind of constrain and what is the proper weight to assign to the Penalty Functions?
thank you
Penalty Functions or Lagrange Multipliers?

Hi noxino,
as you can read in the Help System of the program, "Penalty Functions" have the disadvantage that penalty numbers must be chosen in an allowable range. On this topic you can refer to "Cook et al., 1989".
