Damage Index-Based Lower Bound Structural Design

A NEW DAMAGE INDEX FOR STRUCTURAL DAMAGE IDENTIFICATION BY MEANS OF WAVELET RESIDUAL FORCE

In  this  paper  a  new  method  is  presented  for  structural  damage  identification.  First,  the damaged structure is  excited by short  duration impact acceleration  and then, the  recorded structural displacement time history responses under free vibration conditions are analyzed by Continuous Wavelet Transform (CWT) and Wavelet Residual Force (WRF) is calculated. Finally, an effective d...

energy based structural damage index based on nonlinear numerical simulation of structures subjected to oriented lateral cyclic loading

an energy based damage index based on a new nonlinear finite element (fe) approach applicable to rc structures subjected to cyclic, earthquake or monotonic loading is proposed. the proposed method is based on the evaluation of nonlinear local degradation of materials and taking into account of the pseudo-plastic hinge produced in the critical sections of the structure. a computer program is dev...

Evaluation of Performance Levels of Zipper-Braced Frames Using Structural Damage Index

The determination of structural and nonstructural damage under earthquake excitations is usually considered as a key factor in performance-based seismic design (PBSD) methods is In this regard, various damage indices have been developed in recent years to quantitatively estimate structural damage. The aim of this study is to develop a simple method to evaluate performance levels of zipper-brace...

Iterative Damage Index Method for Structural Health Monitoring

Iterative Damage Index Method for Structural Health Monitoring. (December 2009) Taesun You, B.S., Hanyang University, Seoul, South Korea Co-Chairs of Advisory Committee: Dr. Paolo Gardoni, Dr. Stefan Hurlebaus Structural Health Monitoring (SHM) is an effective alternative to conventional inspections which are time-consuming and subjective. SHM can detect damage early and reduce maintenance cost...
