Development of Analytical Model for Failure Behavior and Nonlinear Load–displacement Characteristic of Piping Support Subjected to Seismic Loading

Abstract

In order to develop analytical model to simulate failure behavior and nonlinear load–displacement characteristic of piping support subjected to excessive seismic loading with high accuracy, case studies were performed focusing on two types of piping support showing different failure behaviors such as buckling and low cycle fatigue. Analytical failure behaviors and nonlinear load–displacement characteristics reasonably agree with the experimental data. The possible reasons for some differences between experimental data and analytical results were discussed. Finally, points for improvement of analytical models were extracted.
