This webinar will explain the alternative diaphragm design force level as well as the precast diaphragm design procedure of ASCE 7-16, which has now been adopted by ACI 318-19, which in turn references two new standards developed by ACI Committee 550: ACI 550.4, Qualification of Precast Concrete Diaphragm Connections and Reinforcement at Joints for Earthquake Loading and ACI 550.5, Code Requirements for the Design of Precast Concrete Diaphragms for Earthquake Motions.

Learning Objectives:

  • Identify the new alternative diaphragm seismic design force level of ASCE 7-16.
  • Explain why the alternative force level was found necessary.
  • Describe how to use the newly introduced diaphragm design force reduction factor.
  • Summarize the new precast concrete diaphragm design provisions of ASCE 7-16.
