Interpretation of test results on prestressed concrete poles
Methods of calculation of cracking and ultimate moments in testing prestressed concrete beams are proposed; basis of first method consists of assumption that concrete takes maximum elongation before beginning of cracks; second method is based on principle accepted by European Concrete Committee that concrete crashes as soon as its shortening reaches maximum value; methods give theoretical results which are in good agreement with tests in case of those prestressed concrete poles which are beams submitted to strong symmetrical prestressing load.
