Code‐Oriented Damage Assessment for Buildings

Abstract

In this study, we present a simple framework for the evaluation of the cost to repair building damage using engineering parameters related to current seismic building codes. Specifically, we envision relationships for building damage repair cost as a function of ground shaking spectral acceleration (Sa at structural period, T), design base shear coefficient (V/W), response modification factor (R), height, and framing system. This framework provides a flexible system for collecting and evaluating building damage from ground shaking, improving the building code, and predicting earthquake damage repair costs to new or existing, or retrofitted buildings, in a wide variety of seismic environments. In the absence of comprehensive statistical earthquake damage data, we resample the ATC‐13 damage database to calibrate an initial damage model. We call the model CODA, for Code‐Oriented Damage Assessment for Buildings.
