“…One of the most common uses of the TZ model is evaluation of the damage risk posed by existing, new, or modified buildings for financial transactions, either for lending or equity investment. In a series of papers in this Journal, methods are discussed to apply the TZ model in a wide range of applications for individual and groups of buildings. Implementation of the reformulated TZR model to determine damageability values for a building includes the following sequential steps: Choose ASTM Level of Investigation. Perform an assessment of the building and site to determine the seismic performance characteristics consistent with the requirements of ASTM for the Level of investigation specified. Select a reference b value corresponding to the type of building and modify it to reflect the specific knowledge and understanding of the building's expected seismic performance.…”

The revised Thiel-Zsutty model predicts the probability distribution function for earthquake damageability of a building as a function of peak ground acceleration and parameters that represent the site soils, building damageability, and uncertainty of the basis for parameter selection. Guidance is provided on how to assign revised Thiel-Zsutty parameters and for procedures to determine these parameters for a given building and site. Parameter base values are given for ASCE 7 structural systems and soil classes. The model includes representation of the uncertainty in the parameter evaluations according to level and quality of investigation through an uncertainty factor. It is keyed to ASTM investigation levels and determined by either a constructive or descriptive approach from the characteristics of the building and its design and construction. Procedures are developed for cases where the damageability factor changes as the buildings or site's response changes its character as the level of excitation increases. Guidance is provided on how to incorporate nonlinear time history analyses for performance-based design of tall buildings and other structures.

“…Robust estimation of the earthquake‐induced losses in the structure‐ and community‐level is the major component of the seismic risk assessment and crucial for decision makers 1–12 . The performance‐based probabilistic seismic loss estimation frameworks available in the literature 13–16 commonly include distinctive components associated with seismic hazard analysis, structural response, damage to the structural and nonstructural components, and resulting losses.…”

SummaryThis paper presents a novel method for estimating the seismic peak interstory drift ratio (IDR) in reinforced concrete (RC) columns after an earthquake using surface crack image analysis. The quantitative representation of the complexity and irregularity of crack images in damaged RC columns is obtained through the consideration of the generalized fractal dimensions. The authors have compiled a comprehensive database consisting of 445 crack maps obtained from cyclic experiments conducted on 110 rectangular RC column specimens exhibiting double‐curvature deformation mode. This database is utilized by the authors to develop and validate the proposed procedure. The research database contains a wide range of structural and geometric features. Five closed‐form equations are developed with the objective of estimating the peak IDR experienced by the RC columns during a seismic event. The predictive equations are derived through the utilization of symbolic regression technique, with the input parameters varying according to the availability of columns characteristic parameters. Results reveal that generalized fractal dimensions, especially D−1, are strong vision‐based indicator of damage in RC columns having correlation coefficients with IDR ranging from 0.82 to 0.92 across the considered plans. The seismic peak IDR obtained through the empirical equations can serve as the input engineering demand parameter (EDP) in the seismic loss estimation frameworks. This allows for the determination of the probability of exceeding damage states for structural and nonstructural components of concrete buildings. Finally, the practical implementation of the methodology is examined by its application to an actual case of a damaged column during the Kermanshah earthquake of magnitude 7.3 that occurred in 2017.
