Title: Experience With Pre- and Post-Cracking Deflections of Pretensioned Members
Author(s): Alex Aswad
Publication: Special Publication
Appears on pages(s): 207-224
Keywords: camber; cracking (fracturing); deflection; deformation; flexural strength; loads (forces); load tests (structural); pretensioning; Structural Research
Abstract:A procedure for rational prediction of deformation in pretensioned members is described. Full-scale load tests on stemmed members spanning 30 to 62 ft (9.2 to 18.9 m) were conducted by the author. They showed good correlation with the proposed predictions. Actual deflections were generally less or close to the computed values. It is suggested that the method may be used for loads not exceeding a certain ratio of the ultimate loads.
