Abstract:
Recommendations are made for the design, manufacture, and erection of precast reinforced concrete floor and roof units having spans of 35 ft (1 1 m) or less. Unit stress, ulti-mate strength, and a test method of strength design are recommended. Recommendations are made regarding bear-ing lengths, bar spacings, minimum reinforcement, and holes. Quality requirements and acceptance procedures are discussed. Prestressed concrete members are not covered in the report.
