DESIGNING POST - TENSIONED BEAMS HAVING SECTIONS WITH COMPRESSION STEEL

THE PURPOSE OF THIS ARTICLE IS TO PRESENT A DESIGN PROCEDURE FOR DESIGNING POST-TENSIONED CONCRETE BEAMS WHOSE STRENGTH IS CONTROLLED BY COMPRESSION. THE SUGGESTED METHOD FOLLOWS THE REQUIREMENTS OF ACI 318-71 AND USES THE PROCEDURES AND TABLE IN THE PCI DESIGN HANDBOOK. IN PRACTICE, A POST- TENSIONED BEAM MIGHT REQUIRE COMPRESSION STEEL AT THE EXTERIOR SUPPORT IF IT IS PART OF A FRAME AND ESPECIALLY EHEN THE TENDON IS ANCHORED AT THE CENTER OF GRAVITY OF THE CONCRETE (WHICH IS THE USUAL CASE). IN ADDITION, A CON- TINUOUS SHALLOW TEE BEAM MIGHT REQUIRE COMPRESSION STEEL OVER ITS INTERIOR SUPPORTS PARTICULARLY IF IT HAS BEEN DESIGNED TO ALLOW TENSION AT SERVICE LOADS. /AUTHOR/
