Resumen
Reinforced concrete frame (RCF) buildings are used worldwide in seismic regions. Nonlinear pushover analysis is central to performance-based assessment of these structures but often demands specialized software and extensive scripting, limiting use in performance based earthquake engineering (PBEE) practice and education. RCF-3D Analysis is a web-based application that generates and analyzes three-dimensional RCF models using OpenSeesPy as backend. A guided, tabbed workflow leads users through building geometry and mass definition, RC material and fiber-section creation, beam column and slab assignment, gravity loading, and modal and pushover analyses. Interactive plan-view visualizations support model checking, while structured data storage enables model reuse. Implemented in Python with Streamlit, RCF-3D Analysis serves practitioners and researchers engaged in PBEE applications.
