Abstract:
As the tilt-up panel is picked up it is subjected to bending that causes both compressive and tensile stresses which must be resisted by the concrete, rein-forcing steel, or a method of strongbacking that prevents the initial bending. Location of the lifting hardware is extremely important as well as the proper use of bond breakers to eliminate excess stresses or possible cracking of the panel during the pickup and erection stage. Recommended practices and field questions and answers are outlined in the article.
