Abstract:
A discussion of the more important points of uncertainity in our knowledge of prestressed concrete concerning which laboratory and field research is needed. There are many quantitive problems of detail which are not discussed; however, the major problems of prinicipal are described. The most important aspect of the problem is concerned with the basic philosphy of design. This involves selecting factors of safetly or load factors, and must be solved before a consistant design procedure can be formulated.
