Prestressed Concrete Beam Camber – 26 Slab
{"Image DocumentName": "Prestressed Concrete Beam Camber \u2013 26 Slab", "Image ImageDescription": "Use a prestress loss of ksi, prestress force = 1091 kips, and strain = Prestress stress after ksi loss = (31)/(0.153) \u2013 = 188 ksi. Use the Moment-Area method to determine the upward deflection of the slab at release. Compute the moment in the slab induced by the eccentric prestressed strands. Strand eccentricity = = 7.64 in. 2. Prestress moment in slab = (1091)(7.64) = 8335 in kips. This moment is assumed to be constant over the full length of the slab, neglecting the effect of debonded strands. Use the Moment Area method to determine the prestress deflection at midspan from the prestress force at release. The deflection is equal to the moment of the area of the M/EI diagram between the end of the beam and midspan about the end support.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
