某钢结构厂房的振动原因分析及经验总结 Abstract Vibrationinasteelstructurefactorybuildingisacommonproblemthatcanaffectthesafetyofworkersandthestructuralintegrityofthebuilding.Inthispaper,weanalyzethecausesofvibrationinasteelstructurefactorybuildingandsummarizeourexperienceinaddressingthisissue.Wefoundthattheprincipalcausesofvibrationinsteelstructuresarethedynamicloadsgeneratedbylargemachineryandequipment,humanactivity,andwindloads.Wealsoproviderecommendationsforpreventingandreducingvibrationinsteelstructurebuildings. Introduction Vibrationisasignificantissuethatcancauseharmtohumans,disrupttheoperationofmachinery,anddamagethestructuralintegrityofbuildings.Steelstructurefactorybuildingsaresusceptibletovibrationduetothepresenceofheavymachinery,humanactivity,andwindloads.Improperdesignandconstructioncanalsoleadtovibrationproblemsinsteelstructures. CausesofVibrationinSteelStructureFactoryBuilding DynamicLoads Dynamicloadsgeneratedbyheavymachinerysuchascranes,forklifts,andconveyorsaresignificantsourcesofvibrationinsteelstructurebuildings.Theseloadscancausethestructuretovibrate,leadingtofatigueandfailureofstructuralcomponents.Themagnitudeofthedynamicloadsdependsontheweight,volume,andspeedofthemachinery.Thevibrationgeneratedbytheseloadscanbemitigatedbyusingvibrationisolators,shockabsorbers,andresilientmounts.
