1609.1.1.2.1 Lower Limits on Main Wind-Forceresisting System

Ohio Building Code 2011 > 16 Structural Design > 1609 Wind Loads > 1609.1 Applications > 1609.1.1 Determination of Wind Loads > 1609.1.1.2 Wind Tunnel Test Limitations > 1609.1.1.2.1 Lower Limits on Main Wind-Forceresisting System
JUMP TO FULL CODE CHAPTER
Base overturning moments determined from wind tunnel testing shall be limited to not less than 80 percent of the design base overturning moments determined in accordance with Section 6.5 of ASCE 7, unless specific testing is performed that demonstrates it is the aerodynamic coefficient of the building, rather than shielding from other structures, that is responsible for the lower values. The 80-percent limit shall be permitted to be adjusted by the ratio of the frame load at critical wind directions as determined from wind tunnel testing without specific adjacent buildings, but including appropriate upwind roughness, to that determined in Section 6.5 of ASCE 7.
