Check RCC and steel material and their grade
Check Mass Source to ensure that 100% DL+FFPW and min 25%LL is included.
Do Not Mesh the walls first. Mesh the Slabs first (3' or 4' min)
Remove Diaphragms first from old model that you are using and make e2k and
import...otherwise there will be error saying over reinforced or OS due CDL etc.
Check Beam defined as beam and column defined as column.
Check Stiffness modifier for beam, column, wall
check frame section for depth, width, clear cover, f'c, steel grade
Ct=0.03/0.029
Check wind and EQ load assignment. Apply wind load up-to roof but not roof top or calculate
roof top load carefully.
10. Check slab as shell thin and Mat as shell thick
11. Check Stiffness modifier for slab
12. check shell element for thickness, f'c etc
13. check wall section for.......
14. assign pier label as required
15. check load cases and combo
16. Assign Dead Load
17. Assign Live load for floor, lift lobby and stair, water tank, gardening etccccc
18. Assign toilet dead load
19. Assign Stair dead load
20. Remove Extra load from roof
21. Assign Restraint at support
22. Use 60/85 as LL for roof considering Rain
23. Release Beam Ends that cannot take moment, otherwise which column will take moment
will not be justified. (Important)
24. Check concrete frame design preference. Check strength reduction factors and seismic
design category(C-in rangs). For ETABS-2018 check B/C capacity ratio to be yes or No.
For SMRF/High rise structures it should be "yes", for IMRF/Normal Buildings "NO"Ref: Humayun Vaiya,,,but be sure.
25. Check rcc overwrites and make sure to be sway intermediate/special.
