Abstract

The influence of ultimate tensile strain (ePSH) fluctuation during the Pseudo Strain Hardening (PSH) behavior on the shear strength and deformation capacity after the flexural yielding of damper with High Performance Fiber Reinforced Cementitious Composite was examined by FEM parametrical analysis. Subsequently, the evaluation methods for shear strength and deformation capacity after flexural yielding, which can give proper consideration to fluctuation of ePSH, were proposed, and their applicability was verified. As a result of comparing the applicability of these evaluation methods with parametric analysis, it was shown that the improvement of the deformation capacity after the shear strength along with the increase of ePSH and flexural yielding could be well evaluated. Furthermore, as a result based on comparison between the test results in the past research and the evaluated value, this proposal equation evaluated all the test results in the past research to be safe.
