“…In many practical applications of RC slabs in engineering structures, the shear response is also of great importance. The research on flexureshear or punching shear response of RC slabs using the layered finite element method has attracted considerable research effort [29,[40][41][42]. Thus the 4-node layered rectangular composite plate element developed in this paper accounts for the membrane-bending coupling of the stretching and bending, and transverse shear effects.…”

“…The layered finite element method has been regarded as an effective method for finite element analyses of reinforced concrete slabs [20][21][22][23][24][25][26][27][28] and has been demonstrated to be effective particularly in predicting the cracking and ultimate behaviour of RC slabs in bending and shear [29]. In the layered plate finite element, the cross section of the composite plate element was divided into a series of concrete layers and the reinforcement was treated as smeared equivalent FRP layers with the stiffness of FRP only in the bar direction.…”

“…The proposed composite FRP-RC plate finite element is based on Mindlin-Reissner plate theory, which has been employed and demonstrated effective for finite element analysis of reinforced concrete slabs [23,26,27,29,34,35]. The accuracy and efficiency of the proposed nonlinear finite element model and analysis procedures are validated by comparing the computed results of a several numerical with those obtained from experimental study and from ABA-QUS.…”

A simple and shear-flexible rectangular composite layered plate element and nonlinear finite element analysis procedures are developed in this paper for nonlinear analysis of fiber reinforced plastic (FRP)-reinforced concrete slabs. The composite layered plate element is constructed based on Mindlin-Reissner plate theory and Timoshenko's composite beam functions, and transverse shear effects and membranebending coupling effects are accounted for. Both geometric nonlinearity and material nonlinearity of the materials, which incorporates tension, compression, tension stiffening and cracking of the concrete, are included in the new model. The developed element and the nonlinear finite element analysis procedures are validated by comparing the computed numerical results of numerical examples with those obtained from experimental investigations and from the commercial finite element analysis package ABAQUS. The element is then employed to investigate the nonlinear structural behavior and the cracking progress of a clamped two-way FRP-reinforced concrete slab. The influences of reinforcement with different materials, ratio and layout in tension or compressive regions on structural behavior of the clamped slabs are investigated by parametric studies.

“…Computer simulation makes the accuracy for describing actual behavior of structure, compare the behavior with laboratory experimenting methods, prospects in the process of scientific research, and relation with experiment and analysis methods. Nonlinear-layered finite element method is capable of analyzing cracking and punching shear failure of reinforced concrete flat plates with spandrel beams or torsion strips [6,7]. It is very important that before practical application finite element analysis methods should be verified and validated comparing the analysis results with reliable experiment data.…”

A finite element simulation for experimental punching shear behavior of reinforced concrete slab is presented in this paper. The numerical simulation is based on previously tested 15 reinforced concrete model slabs. Finite element analysis of reinforced concrete slabs subjected to punching load is evaluated and results are compared with experiments. This study involves development of a nonlinear strategy which implements solution for a realistic description of the deflection, load carrying capacity and crack, pattern related to punching shear of RC slabs for several types of slab thickness, edge restraints, and reinforcement ratio. It has been shown that the load versus. deflection diagram and ultimate load capacity obtained from FE analysis closely match with the experimental results. Comparison of crack pattern of the slab also shows good agreement. It has been shown that using appropriate method and material for numerical simulation, significant benefit can be achieved using finite element tools and advanced computing facilities in obtaining safe and optimum solutions without doing expensive and time-consuming laboratory tests.

Various environmental loadings, such as variation in the ambient temperature, fluctuation of the relative humidity, the exposure to chemically harmful substances, etc., cause the progressive deterioration of the concrete structures. The long-term durability of concrete is largely governed by the resistance of concrete to various physical and chemical processes of deterioration. The interactions between these processes of deterioration become increasingly necessary to be considered in the evaluation of durability.With the fast development of data processing, the digital simulation found an application increasingly extended by modeling various processes of deterioration [1][2][3].However, all these digital models are specific programs describing only the processes considered, which limits their application to a broad variety of applications. Moreover, the analysis of the mechanical stresses induced by the deterioration process did not become available, which makes it impossible to evaluate the influence of acceleration of cracks on the deterioration of concrete and to predict the lifespan of the concrete structure after cracking.
