Prefabricated　cantilevered　beam-column　structures　have　gained　popularity　in　mountainous　road　construction.　However,　a　notable　research　gap　exists　regarding　the　beam-column　connections.　To　fill　this　gap,　a　new　bolted　connection　method　was　introduced　for　the　cantilevered　beam-column　structure.　The　mechanical　performance　of　this　novel　structure　was　systematically　investigated　through　reduced-scale　experiments　and　finite　element　analysis.　The　structure＇s　response　under　three　critical　loading　conditions　was　experimentally　examined,　revealing　the　efficacy　of　bolted　connections　in　preserving　structural　integrity　and　highlighting　pronounced　strain　concentration　at　the　connection　region　of　the　cap　beam.　Furthermore,　to　enhance　structural　design,　a　finite　element　model　of　this　beam-column　structure　was　established　to　simulate　the　influence　of　various　materials　and　structural　parameters　on　structural　response　and　damage.　Simulation　results　indicated　that　the　anchor　rod　angle　and　the　number　of　bolts　had　a　minor　impact　on　load-bearing　capacity　and　damage　modes.　In　contrast,　the　choice　of　concrete　material　and　steel　reinforcement　ratio　significantly　influenced　load-bearing　capacity.　The　insights　derived　from　this　study　offer　valuable　guidance　for　optimizing　and　extending　the　application　of　this　structural　design.　©　2024
