文档介绍:太原理工大学硕士研究譬学位论文在理论分析的基础上,本文利用SAP2000V14分析软件,建立了两个模型,带楼梯的与不带楼梯的模型,对这两个不同的模型进行了分析对比,研究楼梯对框架结构有什么影响;通过对两模型进行的模态分析,得到了两模型的自振周期、质量参与系数,并进行了对比,得到模型的平面设计是合理的,且楼梯提高了框架结构的抗扭刚度;通过对两模型进行的反应谱分析,研究当考虑楼梯的时候,在地震作用与不受地震作用时,结构的各构件所受到的内力的变化、基底剪力、层间位移以及层间位移角的对比:在上述的基础上对楼梯的设计提出了一些建议。关键词:楼梯,框架结构。模态分析,反应谱的分析,SAP2000V14软件太原理工人学硕士研究生学位论文ANALYSISONTHEINFLUENCE0FEARTHQUAKE0NTHES11AIRS0FFRAⅣ,ponentsinseismicdesign,whichusedtodocalculatingandanalysing,onlythestaircasei玎theopenings,ponentsofVertica】,wefoundnoseriousdamageinthemainstructureofmanyframestructurebutthestructurewasseVerelydamaged,,andactsastheroJe,eouttoplayinthenaturaldisasterbefore,unabletoprotecttheiVesa11dpropenysafe哆,therefore,inthestructuredesign,.】re,,thestairswi¨,inthe矗ameworkofbe帅sandcolumnsofthestressdifrerence,}ordancewiththespecificationofconcreteandseismicspecification,modeldoesnotconsiderthestaircaseefrect,model2considertheeⅡ.ectonthe厅amestmctureofthestajrcaSe,p撕sonoftheMomodelsofthesAP2000V46niteelementanalysissofhare,isobtainedbyconsideringthestaircaseof仔amethestmcture,:Onthebasisoftheoreticalanalysis,thispaperestablishedtwomodelsbySAP2000V4analysissof℃war,whichconsideringstairsandwithoutconsideringstairs,,westudyonthestairswouldhaVeanyef-fectonthe行amestructure;Throughmodalanalysiswasconductedontwomodel,haVethenaturalvibrationperiodandtheparticipatingmassratiowithrwomodel,parisonofthem,wegetgraphicdesignwhichisreasonable,andthestairsimproVes
