Committee 320, Safe Loads for Existing Concrete Bridges, was organized (with the author of this paper as chairman) to formulate a procedure for determin- ing the safe loads on existing concrete bridges. The assignment is not an easy one. This paper discusses the committee’s understanding of the assignment and offers a tentative procedure. The problem is complex; it is more difficult to obtain a definite answer than many realize who have been concerned only with design practice. It is impractical to assign definite values to a great number of the unknown and variable factors involved and recommendations must be based on experience, judgment, and perhaps opinion, to a large extent. The prime purpose of the paper is to elicit discussion, to assist the Committee in making its final recommendations.
