Hi, @ronnie9096! you can find the models to download on the website: www.dlubal.com/en/support-and-learning/learning/videos/004924 Just scroll down until you see the section "models to download" :)
Hello, is it possible to perform modal analysis, and consequently spectral analysis, in such a way that masses from the self-weight of the elements, permanent loads, and corresponding imposed loads are concentrated/lumped at story levels (masses and loads from 1/2 of the corresponding story height below and 1/2 of the corresponding story height above) of the model instead of all masses being concentrated in FE mesh nodes (without manually assigning masses of corresponding imposed loads)? Also, if it is possible, how can these concentrated masses at story levels be displayed graphically? Eurocode 8 provides guidelines and recommendations for the seismic design of buildings, but it does not explicitly require that masses be lumped at story levels. However, concentrating masses at story levels can simplify the analysis and is considered good engineering practice in many cases. Thank you in advance for your replay.
Hi, @TheMowieStar! you can achieve such a lumped masses model by using our Building Model with the floor modelling type "rigid diaphragm". This simplifies the model by lumping the masses on the floor level. Also, the masses as described in your question can be visualized there. The building model is treated in the webinar from minute 59:50. For the change to a rigid diaphragm floor type, you would just select the floor modeling type "Rigid Diaphragm" at minute 1:00:34.

If you could share the RFEM file to follow along

@@DlubalENThanks, I had already downloaded from the official website
