“…1). So on the basis of this local analysis approach the influences of reinforcement ratio and arrangement, crack inclination and material properties on the post cracking response of concrete and reinforcement can be investigated numerically (Soltani et al 2005). Figure 2(a) shows the state of stresses of a reinforced concrete element subjected to general in-plane stresses.…”

“…1). This so called "Local Stress Field Approach" was proposed by Soltani et al (2003Soltani et al ( , 2005. The local stress-strain characteristics of concrete and reinforcing bars embedded in concrete, used in this work, are based on the extensive research activities that have been undertaken at the University of Tokyo during the past decades to investigate the fundamental mechanism of local stress transfer in RC domain .…”

“…The computational scheme and general description of the method has been explained in (Soltani et al 2003(Soltani et al , 2005 and can be summarized as follows. (a) The axial and shear deformations of steel bars are obtained by considering the local deformation in the vicinity of cracks.…”

“…Also the shear force carried by reinforcing bars, dowel action, is explicitly calcu- lated by considering the local curvature developed in reinforcing bar in the vicinity of crack. (b) The local stress conditions at crack planes are computed by the amount of local deformation of crack planes using the appropriate material models (Soltani et al 2005). The average tensile stress of concrete between adjacent cracks (tension stiffening) is obtained from the local steel stresses transferred to the concrete body.…”

Despite extensive research on behavior of reinforced concrete in shear, there is still considerable disagreement among researchers in proposing and using a rational way of calculating the shear strength of reinforced concrete members. Due to lack of a universally accepted model for shear, shear design provisions still generally consist of empirical relationships that differ from code-to-code. In this study, a simple rational formula for calculating the shear strength of reinforced concrete elements is proposed by conducting a systematic parametric study on the response of RC elements in shear. This is done by using a computational model which simulates the post cracking behavior of RC membrane element on the basis of local stress transferring mechanism between adjacent cracks and microscopic stress transfer across cracks. Through a comparison with extensive available experimental tests conducted on RC elements, it is shown that the proposed rational relation can appropriately predict the shear strength of reinforced concrete elements under different in-plane stress conditions. Then the proposed relation is extended to the shear design of RC members and again it is shown that the predicted shear strengths are in good agreement with the experimental test results under different combination of axial, bending and shear forces.

To investigate the mechanical properties of dowel action under fatigue loads, 3 reinforced concrete specimens with different bar diameters (12 mm, 20 mm, and 25 mm) were subjected to the fatigue loading and were designed to investigate the attenuation character of dowel action and the fatigue failure modes. e load transfer mechanism of the bond was analyzed based on the 3D relative motions between reinforcing bars and subgrade concrete. Fatigue damage effects were considered in the model. A deterioration coefficient based on the deformation path was defined to represent the accumulation of fatigue damage. Verification of the model was conducted by comparing the analysis results with experimental data obtained in this study and from the literature, and satisfactory agreement was obtained.
