FM-2D - open-source platform for the 2-dimensional numerical modeling and seismic analysis of buildings
Abstract
Computer tools have been recently become available to simplify the implementation of the challenging probabilistic performance-based earthquake engineering (PBEE) framework. Although, these tools assist the user with most of the PBEE definitions (e.g., damage fragility and seismic hazard), they still require the user to provide structural response data. This can be a tedious and demanding task particularly when aiming to obtain robust data by means of nonlinear response-history analysis of detailed numerical models. To that end, an open-source MATLAB-based platform is developed herein to streamline this process. The platform implements state-of-the-art nonlinear numerical modeling recommendations for members and connections and pertinent dynamic analysis methodologies while supporting modeling uncertainty consideration. This is all packaged within intuitive graphical user-interface modules and supported with comprehensive options for visualizing the global and local structural response data.
