Structural Damage Detection (SDD) using FCN

this project is based on tsai

This project tries to detect structural damages (stiffness reduce) of a four floor frame

Project tree

frame_data - matlab codes for data generation

frame_test.ipynb - Colab file for training and testing

For data to train FCN, please run matlab codes data_generation.m in frame_data folder.

Simulation

The four floor frame used is as the follow:

Force was applied to the first floor using a half-sine wave with the period of 5.0sec, and the maximum force is 100N.

Time histories analysis was implemented using newmark's $\beta$ method according to Modal Time History Analysis of Structuresby Tazarv et al. One of results is as folows:

FCN

FCN is used to do the task of structural damage detection, which, in fact, is a multi-label classification problem based on time series. The artitecture of FCN is as follows according to Fawaz et al
