Parametric Seismic Assessment of informally constructed Masonry-Infilled RC Frame Archetypes Considering Structural Variability

This repository contains the data and scripts used to derive analytical seismic fragility functions for informally constructed reinforced concrete (RC) frames with unreinforced masonry (URM) infill walls representative of low-rise housing in Colombia. The dataset accompanies a study on the seismic vulnerability of informal dwellings in the Sabana Centro region and includes the numerical models and results used to generate fragility curves for multiple structural archetypes. The repository contains the following files: 1. Fragility parameters dataset (Excel file)The spreadsheet contains the parameters of the fragility functions obtained for each structural archetype. For every damage state, the following parameters are reported: Median intensity measure (θ) Logarithmic standard deviation (β) Each row corresponds to a specific archetype generated in the study. 2. Archetype definition and model parameters (PNG file)This file describes the parameters varied to generate the archetypal structures, including: Column cross-section dimensions Longitudinal reinforcement ratio Stirrup spacing Number of stories Wall configuration Building weight These parameters define the variability considered in the analytical study. 3. OpenSeesPy modeling and analysis script (Python)The Python script used to generate the nonlinear structural models and perform the seismic analyses using OpenSeesPy.The script includes: Definition of materials and fiber sections Modeling of RC columns and beams Representation of URM infill walls Gravity load analysis Nonlinear pushover analysis Requirements Python 3.10+ Required packages: openseespy numpy matplotlib joblib
