Paper Title:
High Performance Precast Wall Panels with Shear Transfer Provided by Carbon Fiber Grid
  Abstract

Composite insulated wall panels using carbon fiber grid in combination with expanded polystyrene (EPS) insulation have been produced for over 5 years. The carbon fiber grid and the EPS act together to provide shear transfer between the wythes of the composite panel. A design procedure has been developed, based on testing at Washington University and North Carolina State University. The approach discussed here is to ensure that the flexural strength, the cracking moment, and the deflection are all within acceptable limits. This paper first discusses the testing that has been performed to develop the material properties used in the design procedure. Then methods for computing the flexural strength, the cracking moment and the deflection are also presented. Deflections are not often an issue and cracking moments can be easily controlled by the amount of prestress. Therefore, the most important concern is providing adequate shear transfer. The design procedures discussed here were later verified by full scale testing at North Carolina State University.
