Abstract
This thesis investigates the behavior of Steel Moment-Resisting Frames (SMRFs) with rigid bolted joints and proposes seismic design rules for their components. It comprises several chapters on (i) presenting and interpreting the results of shake-table tests conducted on four steel moment-resisting frames having different European prequalified joints, with and without nonstructural elements; (ii) investigating the behavior of European 10.9 steel HR and HV bolts under tension and bending; (iii) proposing seismic design rules for wide-flange steel columns; (iv) introducing Reduced Column Section and Buckling-Restrained Web System column base topologies; and (v) studying the effects of joint type and indirect composite action on the seismic performance of SMRFs. Each chapter presents advanced numerical modeling procedures tailored to the specific problem under investigation. Some of the tools and code developed in this research are also publicly available in an online repository. The findings provide several novel insights that enhance understanding of SMRF behavior and can contribute to the development of next-generation steel design codes.
