seismic design base shear
(OP)
Where you are required to show the seismic design base shear on the drawings, should you show the total value or the diaphragm value? Thank you much.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: seismic design base shear
The diaphragm value is a special shear at ONE level only, that is predicated by a min. and max. limit as well as offset vertical brace lines, etc.

WHY IS THIS REQ'D ON DRAWINGS BY IBC?
RE: seismic design base shear
It also provides future engineers with some quantative data for future analysis should the owner decide to alter the building somehow.

OK USING THE SAME LOGIC IF IT IS SO IMPORTANT THEN WHY DON'T I PROVIDE IT FOR WIND DESIGN AS WELL.
RE: seismic design base shear
For wind design, I believe the code requires the design wind speed and exposure to be stated (we do on every project)
IBC 2000 -section 1603.1.4 calls for the following info to be placed on the drawings:
1. Basic wind speed
2. Wind importance factor
3. Wind exposure
4. Internal wind coefficient
5. Component and cladding pressure for elements not designed by the engineer.
