The course on Hollow Core Diaphragm Design provides a review of the code requirements from IBC 2015, ASCE 7-10, and ACI 318-14 for the design of diaphragms in general. The provisions are applied to precast concrete hollow core construction. A design example following the PCI Manual for the Design of Hollow Core Slabs and Walls is presented that covers diaphragm design for wind, low-risk seismic design (SDC B) and moderate risk seismic design (SDC C).

Learning Objectives: 

• Understand rigid and flexible diaphragms
• Calculate the diaphragm design force in accordance with ASCE 7-10
• Understand the diaphragm design provisions of ACI 318-14
• Be familiar with diaphragm behavior and design with hollow core slabs.
