## Overview

This repository supports research on reduced-order seismic design of suspended piping systems. The main workflow is to run an archetype’s 2D equivalent-linear-static pushover, which delegates model and procedure work to shared functions and writes displacement, force, and modal-result rows. Separate archetype-specific SDOF scripts perform nonlinear pushover analyses. Supplied result files and notebooks preserve displacement and displaced-shape outputs for review. The excerpts show the 2D runner’s call and output, but not the notebooks’ data-loading details, so those links are left unspecified.
