EXAMPLE 10.8 The end block of a post-tensioned prestressed concrete beam, 300 mm wide and 300 mm deep, is subjected to a concentric anchorage force of 832800 N by a Freyssinet anchorage of area 11720 mm². Design and detail the anchorage rein- forcement for the end block. Prestressing force, P = 832800 N Average compressive stress, EXAMPLE 10.8 The end block of a post-tensioned prestressed concrete beam, 300 mm wide and 300 mm deep, is subjected to a concentric anchorage force of 832800 N by a Freyssinet anchorage of area 11720 mm².
