Title: A Method of Predicting Crack Widths and Deflections for Fatigue Loading
Author(s): P. Balaguru and S. P. Shah
Publication: Special Publication
Appears on pages(s): 153-176
Keywords: beams (supports); crack width and spacing; creep properties; deflection; fatigue (materials); fatigue tests; reinforced concrete.
Abstract:With the increasing use of reinforced concrete for offshore structures, it is necessary to know the service behavior in addition to the ultimate behavior of beams to fatigue loading. An analytical method is presented here to predict the increase in deflection and crack width for concrete beams. The method is based on some available information on the fatigue properties of plain concrete, reinforced concrete beams and the ACI-design methodology for static loading. The analytical model is used to perform a parametric, and is compared with the CEB-FIP code equation and some available experimental data. The proposed method could be further improved as additional experimental data becomes available.
