Показать описание
Correction: At time 52:19, when Vt is less than 0.85V, the 0.85 factor should be applied to the base shear.

This webinar utilizes Dlubal's powerful finite element analysis program RFEM.

Content:
- Introduction to the RF-DYNAM Pro add-on modules
- Analysis of natural frequencies and mode shapes
- Perform a response spectrum analysis according to the IBC 2012 / ASCE 7-10
- Apply generated equivalent static loads in RFEM

Best tutorial I have seen on natural vibrations and the equivalent loads method. Thank you very much

Great webinar, thank you!
But is it really correct for analysis when (at the 45:30) you made a user result combination with load cases LC1, LC2, LC3 combined with the dynamic load case DLC2 ?
Though in RF-DYNAM Pro you have calculated masses from combination with LC1, LC2, LC3 (at the 12:00), so each dynamic load case already includes these load cases, or doesn’t it?
In this (your) version of analysis won’t RFEM calculate these load cases twice?

why is the action category under dyanmic load is being displayed under action category dead for load cases considered? isn't that it should be under earthquake/seismic.?

what about the factor i/r where to apply it according to (12.9.2 Modal Response Parameters) ASCE10
