EaRL—Software for Earthquake Risk, Loss and Lifecycle Analysis

Performance-based earthquake engineering (PBEE) has become an increasingly popular framework to design, retrofit and manage structures. This probabilistic framework integrates data from the seismic hazard, structural response, damage fragility and damage consequences to compute structural performance metrics; thereby facilitating an effective communication to building owners and stakeholders besides the engineering community. In support of PBEE, a Matlab-based computational platform/software is developed that implements state-of-the-art loss estimation and seismic lifecycle analysis methodologies. The software aims to (1) facilitate the relatively challenging PBEE computations by providing an intuitive graphical user-interface, a wide range of data visualization options and collective features that adapt to different users’ preferences; and (2) provide an open-source platform for code and software development to support the continuously advancing aspects of the PBEE framework.
