Cyclic load displacement and design variable database of square and rectengular columns

This database compiles cyclic load displacement data and design variables for 150 square and rectangular reinforced concrete (RC) columns, focusing on conventional RC construction with concrete compressive strength up to 50 MPa. It includes 140 curated test data from the "NEES: ACI 369 Rectangular Column Database" (available at https://datacenterhub.org/resources/255) and the "PEER Structural Performance Database" (available at https://nisee.berkeley.edu/spd/). An additional 10 data points were digitized from recent literature. Unlike the source databases, which cover all concrete grades, this dataset is tailored to represent the majority of urban RC building stock. It is designed to support future studies, particularly for calibrating empirical models for nonlinear analysis of RC frame buildings constructed with concrete up to 50 MPa.
