Load history deflections utilize detailed time-dependent curvature calculations on the cross section. Influence of creep, shrinkage, cracking, and load history effects are included. Additional information on the detailed cross section calculations was presented by Hirsch [Hirsch, J., "Accurate Long-Term Deflection Prediction in Flat Slabs Using Linear Elastic Global Analysis", 24th Biennial Conference of the Concrete Institute of Australia, Sydney, Australia, 2009, 11 pp.].
