This dissertation was initiated to investigate the behavior of load-bearing concrete insulated wall (CIP) panels for use in tilt-up construction under combined axial and out-of-plane loading. Currently, the building code does not address the design of these panels. Testing solid concrete panels and CIPs of 40 ft span, a length typical of contemporary construction, was critical to observe such slenderness ratios and identify significant second-order panel behavior. A modified version of the slender wall design method to predict second-order load and deflection behavior in the post-cracking range in CIPs was proposed. Additionally, horizontal shear failure analysis methods were investigated to enable design against such failures. Another method termed the K123 method was demonstrated that can better predict panel deflections and horizontal shear failures using matrix analysis or other methods. These methods were validated against experimental and 648 OpenSees models. The findings of this research are being used to develop a design guide for concrete insulated panel by Tilt-Up Concrete Association.
