“Development of Risk- Targeted Earthquake Ground Motions for use in ASCE 7,” N. Luco, USGS March 11, 2011. From site-specific procedures (Chapter 21) of. “Development of Risk- Targeted Earthquake Ground Motions for use in ASCE 7,” N. Luco, USGS March 11, 2011. Chapter 11 SEISMIC DESIGN CRITERIA 11.1 GENERAL 11.1.1 Purpose. Chapter 11 presents criteria for the design and construction of buildings and other structures subject to earth-quake ground motions. The specified earthquake loads are based upon post-elastic energy dissipation in the structure, and because.
ASCE 7-10 Wind Loads
ASCE 7-10 Wind Loads
What was the purpose of switching the wind provisions from ASCE7-05 from allowable to strength methods in ASCE 7-10? IBC requires you to calculate wind loads in accordance with ASCE 7-10 but then requires you to calculate a Vasd?????? and Vasd is the determining factor when you get into the Structural Observations for Wind Requirements of chapter 17. Not to mention that now all of my allowable wind drift and deflection limits (H/400 under allowable loads ect.) are all different because of the increase in the wind speed.
Very frustrating.
