This book introduces analytical methods to investigate the influence of material properties, construction sequence, and time-dependent effect on the performance of concrete flat slab systems. Emphasis was placed on implementation of material constitutive model, cracking, and deflection of slabs under service load conditions. In order to investigate the early age effect of concrete, an experimental program was performed for one-way reinforced concrete slab.

This book introduces analytical methods to
investigate the influence of material properties,
construction sequence, and time-dependent effect on
the performance of concrete flat slab systems.
Emphasis was placed on implementation of material
constitutive model, cracking, and deflection of
slabs under service load conditions. In order to
investigate the early age effect of concrete, an
experimental program was performed for one-way
reinforced concrete slab. Results of this study help
to provide recommendations for improved design of
concrete slab systems. The UMAT defined in
ABAQUS/Standard is used to idealize material
behavior. Time-dependent effects are implemented
along with tension stiffening models. Laboratory
tests on nine simply supported one-way reinforced
concrete members subjected to sustained load was
performed. The test results demonstrated the effect
of shrinkage restraint provided by embedded bars on
the flexural cracking of the specimens under applied
load, as well as effects of early age loading on
time-dependent response.
