Studies from Sharif University of Technology Have Provided New Information about Structural Engineering (Performance-based seismic assessment of steel frames using endurance time analysis)

By a News Reporter-Staff News Editor at Journal of Engineering -- Investigators publish new report on Structural Engineering. According to news reporting out of Tehran, Iran, by VerticalNews editors, research stated, "The current performance-based seismic assessment procedure can be computationally intensive as it requires a large number of time history analyses (THA) each requiring time intensive post-processing of results. This study proposes the endurance time analysis (ETA) method as an alternative method to THA and incremental dynamic analysis (IDA)."

Our news journalists obtained a quote from the research from the Sharif University of Technology, "ETA is a time history based dynamic pushover procedure that applies a set of gradually intensifying acceleration functions to the structure and monitors the performance of the building accordingly. In this paper, the application of ETA in the seismic assessment of multistory steel concentrically braced frames is compared with THA and IDA methods. Moreover, the progressive failure of the frames is investigated using the ETA method."

According to the news editors, the research concluded: "The results of this analysis show that ETA can estimate THA as well as IDA, with considerably less computational effort."
