## Model Description

### Model Form

This model predicts damage ratio in Concrete Intermediate Moment Frame Interior Joint: $${\Phi^{-1}}(\eta) = {\theta_1}\cdot(\ln(\delta) - 4.48( \ln({{d_b} \over {l_b}} ) +9.055{{d_b} \over {l_b}} )) + 30.415 {{d_b} \over {l_b}} + 3.3\ln({{d_b} \over {l_b}}) + \epsilon \cdot \sigma$$ where, $${\Phi^{-1}}$$ is the probit function.
