Seismic Fragility of RC Bridge Columns: 300-Sample Pushover/Dynamic Datasets and Trained ANN Surrogates (MATLAB)
Listed in Teesside University Research Data Repository
Overview: This dataset supports a series-distributed artificial neural network (ANN) framework for developing seismic fragility curves of reinforced-concrete (RC) bridge columns with reduced computational cost.
Description
It contains four curated datasets (300 samples each) generated from nonlinear pushover and time-history dynamic analyses for rectangular and circular sections, six pre-trained ANN surrogate models, and MATLAB scripts to perform Monte Carlo–based fragility assessment.

Code (MATLAB .m) mc_based_fragility.m (main driver), fragility.m (helper), and utilities for parameter fitting (fn_mle_pc.m, fn_mle_pc_probit.m, fn_sse_pc.m). Methods in brief: Ground-motion–intensity relations, drift demands, and damage-state thresholds are learned via coupled ANNs trained on the provided analysis results. The trained surrogates are then integrated with Monte Carlo simulation to produce fragility functions across multiple limit states without assuming a lognormal form.
