[rachidammoury]

Hi, 

first of all sorry for my english.
ok i am modeling a building with 50 stories each 10 stories are differents.
for preventing errors, each 10 stories i draw than i run calculation and see results (Only added selfweight)
ok for the first 6 basement look at the mass, compare it to the Floors F1 to F10 it is verry small 
and the biggest problem that F10 to F 20 are equal to 0
please help!!

Hi, my suggestion is to display the load table and check the bar list in the self weight row. Probably the self weight was assigned only to the first 10 stories.

In the main window of geometry of the structure press ctrl+a, then select the list in the object selector and press ctrl+c. Go to the load table, select the list cell and erase the content, then press ctrl+v.

Run the analysis and check the results.
