Experimental and numerical analysis of the strain-rate effect on fully welded connections

Cyclic Response of a Steel Beam-to-Column Connections – An Experimental and Numerical Study

“…An extensive discussion on the loading protocols was presented by Krawinkler [11]. This is a very important and difficult issue as on one hand it is believed that it influences the resulting performance and on the other hand it poses demands on the capabilities of the experimental facility [6,7,8,11,12,15]. As this work at its present stage aims to produce results that will be utilized for validating the numerical capabilities of existing software rather than checking the validity of code provisions the used loading protocol does not comply exactly with ones suggested by Krawinkler and other researchers [6,7,11,15].…”

“…The first type of tests is generally referred as high cycle fatigue (HCF); these tests typically involve more than 10 6 cycles to cause failure. The second type of tests is named low cycle fatigue (LCF) test and the number of cycles to failure generally ranges from 10 2 to 10 4 cycles and this is usually employed for testing the seismic performance of steel beam-to-column joints [6,8,11,12,15].…”

“…Similar studies have been performed in the past by other researchers. Despite the fact that many similar experiments have been performed in the past [6,8], the current experimental investigation was considered as necessary in order to provide at first hand all the information required for the numerical analyses. That is, the exact geometric and material characteristics of the specimens as well as specific information on the type of loading conditions and on the measured response.…”
