In SimCenterBackEndApplications-master/modules/createSAM/MDOF-LU/Building.h, there's a particular line of code whose origins I was wondering about (attached here) pertaining to the lambda calculation.
It appears to be a regression relationship used in place of performing an eigen analysis to obtain lambda every time the code is run. I just wanted to inquire to see if any further information is available regarding how this regression may have been determined in the first place.
Thanks in advance.

I contacted Prof. Lu. It is based on regression. The relevant info is shown in the attached image which is a screen shot of what he sent.
The details of the calculation of lambda can be found in Appendix A of Lu X , Han B , Hori M , et al. A coarse-grained parallel approach for seismic damage simulations of urban areas based on refined models and GPU/CPU cooperative computing[J]. Advances in Engineering Software, 2014, 70:90-103.

Thank you for reaching out to Prof. Lu to clarify that, very helpful to know.
