Crack-Based Damage Assessment Method for HSRC Shear-Critical Beams and Columns

Crack-Based Damage Assessment Method for HSRC Shear-Critical Beams and Columns The main purpose of this study is to propose a crack-based damage assessment method for high strength reinforced concrete (HSRC) shear-critical beams and column members. At first, the monotonic models of the force-deformation relationship for HSRC shear-critical beam and column members are proposed on the basis of the mechanical behavior, including four points: the cracking point, maximum strength point, degradation point, and axial failure point. For the nonlinear dynamic analysis, hysteretic rules are suggested and investigated using the full-size experiment including the HSRC beam and column specimens. Furthermore, on the basis of the experimental results, the relationship between the residual deformation and the residual maximum shear crack width is constructed. Finally, the experimental results are used to investigate the application of the proposed crack-based damage assessment method for HSRC shear-critical beam and column members. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Advances in Structural Engineering SAGE

Abstract

The main purpose of this study is to propose a crack-based damage assessment method for high strength reinforced concrete (HSRC) shear-critical beams and column members. At first, the monotonic models of the force-deformation relationship for HSRC shear-critical beam and column members are proposed on the basis of the mechanical behavior, including four points: the cracking point, maximum strength point, degradation point, and axial failure point. For the nonlinear dynamic analysis, hysteretic rules are suggested and investigated using the full-size experiment including the HSRC beam and column specimens. Furthermore, on the basis of the experimental results, the relationship between the residual deformation and the residual maximum shear crack width is constructed. Finally, the experimental results are used to investigate the application of the proposed crack-based damage assessment method for HSRC shear-critical beam and column members.
