Monte Carlo simulation for uncertainty propagation with SAP2000 OAPI and MATLAB

The script performs a Monte Carlo simulation of a structural model which is previously defined in Sap2000.
The script requires as inputs:
- a Sap2000 .sdb model;
- a set of N values of uncertain parameters, sampled according to the user-defined probability density function.
The script computes the response of the structural system for each sample of parameters, and save it in a .mat file, together with the coordinates of the nodes and the connectivity matrix. The data can be then retrieved to study uncertainty propagation.
Different types of analyses (static, modal, dynamic) can be chosen.
Warning: the script is written for Sap2000 version 19; for different versions, the script should be changed accordingly (change all "SAP2000v19").
