Title：ResearchonthePerformanceofSemi-rigidConnectionNodesforSteelBeamsandColumnsinWeakAxisDirectionwithWavedFlangePlates
Introduction：
Steelstructuresareapopularconstructionchoiceduetotheirhighstrength,durabilityandarchitecturalflexibility.Steelstructuresaretypicallyassembledusingboltsorwelding,whichcreatefullyrigidorfullypinnedconnectionsbetweenmembers.However,inreality,manyconnectionsexhibitsemi-rigidbehaviorduetothedeformationcharacteristicsofthecomponents.Thesemi-rigidconnectionisatypeofstructuralconnectionthatcanbothtransmittheloadandallowforacertaindegreeofrelativedeformationbetweentheconnectedmembers.
Objective：
Theobjectiveofthisstudyistoinvestigatetheperformanceofsemi-rigidconnectionnodesforsteelbeamsandcolumnsintheweakaxisdirection,utilizingwavedflangeplates.Throughexperimentalandnumericalsimulationmethods,thisstudyaimstoanalyzetheeffectsofthewavedflangeplateontheconnection'sstiffness,strength,anddeformationbehavior.Furthermore,thestudywillexplorethemechanismsofthesemi-rigidconnectionandprovidesuggestionsforoptimizeddesignandconstructionpractices.
