Design and construction details are presented on precast concrete wall panels of sandwich panel deign. While most precast concrete sandwich wall panels to date have been factory fabricated in relatively small panels, advantages are cited for casting large sandwich panels for tilt-up construction. Details are given on various types of sandwich panels. Some fundamentals of deisgn for conventional sandwich walls are given with simple calculations. An example wall is designed for tilt-up construction. Incorporation of prestressing in such a panel is discussed. A cost analysis is also included.
