Title: Deflection of Prestressed Concrete Beams with Openings
Author(s): Teresinha do M. J. Alves and Andrew Scanlon
Publication: Special Publication
Appears on pages(s): 215-230
Keywords: beams (supports); cracking (fracturing); deflection;
moments of inertia; openings; prestressed concrete; structural
Abstract:Load-deflection response of prestressed concrete beams with web openings is determined analytically by means of a truss model that includes the effects of progressive cracking. Post-cracking response is based on application of the effective moment of inertia concept. Good agreement between analytical results and experimental results in the service load range is indicated.
