The revised Thiel-Zsutty earthquake damage model-Reformulated and extended-Part 2 (original) (raw)

Structural Design of Tall and Special Buildings, 2017

Abstract

SummaryThe 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.
