Multidisciplinary Tool for Evaluating Strengthening Designs for Earthquake-Prone Buildings

Abstract

In many seismically active countries, there is a high level of earthquake risk because of the presence of large stocks of earthquake-prone buildings. The typically high cost of earthquake retrofit and the difficulties associated with satisfying the interests of multiple stakeholders within a meaningful time frame potentially result in building demolition as the default seismic risk reduction solution. The Heritage Evaluation Framework (HEF) is a multidisciplinary decision-making tool to guide proposed seismic retrofit design by gathering inputs from all project stakeholders and to evaluate a particular seismic retrofit design against client expectations. The performance of the HEF is demonstrated for two retrofit projects using input data acquired via interviews, site walkthroughs, and regular meetings with project teams and clients. Results show that the HEF accommodates conceptual designs and provides useful feedback while encouraging early multidisciplinary collaboration.
