For a SMRF(special moment resisting frame) system, the earthquake lateral force is primarily resisted by girders and columns. Thus, they must be designed in consideration of earthquake provision in the code.
If you are new to earthquake code per ACI or NSCP, this spreadsheet has Notes beside the formulas to let you know what section it is located in the code. Thus, this helps in guiding you what important provision is really used in the code and you avoid reading too much unnecessary provisions.
Again, green values are linked from the Design Criteria tab. You just need to input(red fonts) the STAAD member forces and this spreadsheet will give you:
- required top and bottom bars
- hoops spacing from shear forces
- stiffener requirement
- and verification of section of beam assumed
