Numerical investigation of the robustness of extended end-plate bolted beam-to-column joints subjected to column removal

Abstract

Emphasis on the study of robustness of structures have gained attention after the famous collapse of infrastructures over the years. After the 9/11 World Trade Center incident, a drastic increase on researches on progressive collapse and the role of catenary action have occurred, indicating the urgency of focusing the efforts of engineers on designing blast-resistant buildings. Aside from terror attacks, robustness of structures is deemed significant for designing structures against natural catastrophes. In this study, the joints are given focus in designing moment-resisting steel frames. It is the aim of this study to analyse the robustness of steel joints using a typology that was typically used for regions with high seismicity. Hence, the use of MRF and larger column sizes. This was done by simulating a local joint under sudden loss of the middle column in ABAQUS.
