Title: Model Study of Cracking of Prestressed Concrete Flat Plates
Author(s): P. R. Chadrabarti
Publication: Special Publication
Appears on pages(s): 133-156
Keywords: cracking (fracturing); crack propagation; flat concrete plates; models; post-tensioning; prestressed concrete; unbonded prestressing; tests; Structural Research
Abstract:An attempt is made to study the crack formation, crack propagation, and the postcracking behavior until failure of four-panel prestressed concrete flat plates having two-way continuous parabolically draped unbonded post-tensioning tendons. The test specimens closely simulate the corner panels of an actual flat plate floor system having simple supports along the edges. The simple support system is similar to that provided by ledger beams or walls. The effect of added mild steel on the crack initiation, crack propagation, crack width control, and postcracking behavior is also studied. Recommendations are also made for further research.
