抗震结构设计在高层建筑中的应用分析
Title:ApplicationAnalysisofSeismicStructuralDesigninHigh-riseBuildings
Introduction:
Theimportanceofseismicstructuraldesigninhigh-risebuildingscannotbeoverstated.High-risebuildingsareespeciallyvulnerabletoearthquakesduetotheirheight,flexibleconstructionmaterials,andcomplexstructuralsystems.Therefore,athoroughunderstandingoftheprinciplesandstrategiesofseismicdesigniscrucialtoensurethesafetyandintegrityofthesestructures.Thispaperaimstoanalyzetheapplicationofseismicstructuraldesigninhigh-risebuildings,exploringvariousaspectssuchasbuildingcodes,designconsiderations,andinnovativetechnologyused.
