Simplified method of seismic damage prediction and visualization for R/C building structures

To evaluate visible seismic damage of reinforced concrete (R/C) members such as crack width and length, predictive models are proposed to quantify each crack width and corresponding length. These models are intended to apply to the earthquake response employing the simple and well-known analytical model such as one component model or fiber model in order to design the reparability performance of building structures. The proposed models are verified employing various test results. Crack length can be schematically estimated the crack pattern. On the other hand, crack widths can be approximately estimated corresponding to the residual drift through the geometrical model.
