A novel modular system for pipe racks using friction-slip connections

Pipe racks provide essential support for pipelines and equipment in industrial complexes. An innovative modular design method is proposed in this study, where each module is designed to bear gravity and lateral loads independently. To enhance seismic performance, friction-slip connections, consisting of two circular plates bolted to each other and welded to beams and columns, are utilized. A rigid modular pipe rack was modeled in ETABS for …
