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.
