Abstract:
This thesis explores the domain of steel connections, focusing on the optimization of end-plate bolted beam-to-column configurations for moment-resisting steel frames. While the European design code EN 1993-1-8 provides the foundation for the widely used two bolts-per-row connection, this research aims to enhance performance under extreme loading conditions. Through an extensive experimental study, 30 macro-component specimens representing top and second bolt-rows in extended end-plate connections were tested and analyzed.
Varied parameters, including bolt diameter, end-plate thickness, flange width, and bolt disposition, were systematically explored. An extensive numerical investigation scrutinized elasto-plastic behavior, offering crucial insights into the system's response. By comparing the performance of four bolts-per-row configurations against the classic two bolts-per-row solutions, this study contributes to advancing the understanding of steel connection behavior under challenging conditions. The findings aim to redefine design paradigms, promoting more resilient and adaptive structures in the field of steel construction.
