TORSIONAL STIFFNESS OF REINFORCED CONCRETE GIRDERS (PART 2)

项目名称：	TORSIONAL STIFFNESS OF REINFORCED CONCRETE GIRDERS (PART 2)
摘要：	IN 1970, IN ACCORDANCE WITH THE ORIGINAL TEST PLAN, CONCLUSIVE TESTS WERE UNDERTAKEN WHICH DEALT PARTICULARLY WITH THE QUESTION OF THE SIMILARITY (2 OF 4 TESTS CARRIED OUT) AND THE ACTION OF TORSIONAL REINFORCEMENT UNDER 45 DEGREES. FOR THE OTHER 2 SIMILARITY TESTS AND THE 2 TESTS WITH T AND L CROSS SECTIONS THE TEST RIG HAD TO BE RE-BUILT. THE TEST SAMPLES WITH REINFORCEMENT ARRANGED AT 45 DEGREES OR LESS FAILED BECAUSE THE TENSILE YIELD POINT OF THE REINFORCEMENT WAS REACHED, ALTHOUGH THEY ONLY CONSISTED OF CONCRETE B 250, WHEREAS IN EARLIER COMPARATIVE BEAMS WITH ORTHOGONAL REINFORCEMENT MADE OF CONCRETE B 500 THE CONCRETE STILL FAILED.
