6. Model Building and Analysis

The modeller class builds and analyses stick-and-mass MDOF structural models using the OpenSees framework. Each storey is represented by a Pinching4 hysteretic spring. Supported analysis types include gravity analysis, modal analysis, static pushover (SPO), and nonlinear time-history analysis (NRHA).
