Development and Investigation of the Ultimate Load Behaviour of Post-tensioned Brickwork Beams
This paper describes the development of post-tensioned brickwork beams and their behaviour up to failure under short-term loading. The brickwork section was specially designed for ease of construction and grouting of the tendons. The test results of 15 post-tensioned beams, with spans ranging from 2 m to 6 m, are given. The ultimate moments obtained from the tests are compared with the theoretical moments derived from a simplified cubic parabolic stresdstrain relationship of the brickwork, and it is shown that the ultimate moment of post-tensioned brickwork can be closely predicted by this method.
