• MECHANICAL MODEL FOR DIRECT SHEAR FAILURE OF CONCRETE : Prediction for entire load-displacement characteristics

抄録

The objective of this paper is to develop a mechanical model fbr direct shear failure of concrete, focusing on the entire load-displacement characteristics The method makes use of rotated smeared crack model, truss model theory and interlocking shear transfer model, combined in a simple model. The analysis employs the development of multiple diagonal cracks under far field uniform shear stress and macroscopic shear crack propagation The model is verified through the comparison of the model's prediction with both experimental measurements and nonlinear Finite Element Method (FEM) analysis results The model is found in good agreement with both experiments and FEM analysis, indicating that it can be used as a reliable tool for reasonable first estimate for the response. Specifically, the mechanical model can capture the complicated transition behavior although FEM analysis can not account for it. Finally, the present analytical study qualitatively shows the interaction between macroscopic shear strain softening phenomena and interlocking phenomena at the post-peak regime
