Punching shear database and analysis code for opening-adjacent slab–column connections

Experimental database, analysis code and design tool accompanying the article "Capacity loss and recovery at opening-adjacent slab–column connections: a closed-form design equation with partial factors". The database contains 296 records compiled from 33 experimental studies, of which 80 specimens from 11 studies enter the model set after definition harmonisation and scope filtering. All exclusion decisions are documented in the accompanying log. The package includes the full analysis pipeline, the reference implementation of the proposed equation, and a single-file browser tool for design calculations.
