延安市政府办公楼摘要本工程为政府办公楼工程，采用框架结构，主体为六层，本地区抗震设防烈度为8度，近震，场地类别为II类场地。主导风向为西南，基本风压0.40KN/M，基本雪压0.25KN/M。楼﹑屋盖均采用现浇钢筋混凝土结构。本设计贯彻“实用、安全、经济、美观”的设计原则。按照建筑设计规范，认真考虑影响设计的各项因素。根据结构与建筑的总体与细部的关系。本设计主要进行了结构方案中横向框架第12轴抗震设计。在确定框架布局之后，先进行了层间荷载代表值的计算,接着利用顶点位移法求出自震周期，进而按底部剪力法计算水平地震荷载作用下大小，进而求出在水平荷载作用下的结构内力（弯矩、剪力、轴力）。接着计算竖向荷载（恒载及活荷载）作用下的结构内力。是找出最不利的一组或几组内力组合。选取最安全的结果计算配筋并绘图。此外还进行了结构方案中的室内楼梯的设计。完成了平台板，梯段板，平台梁等构件的内力和配筋计算及施工图绘制。对楼板进行了配筋计算，本设计采用桩基础，对基础承台和桩进行了受力和配筋计算。整个结构在设计过程中，严格遵循相关的专业规范的要求，参考相关资料和有关最新的国家标准规范，对设计的各个环节进行综合全面的科学性考虑。总之，适用、安全、经济、使用方便是本设计的原则。设计合理可行的建筑结构方案是现场施工的重要依据。关键词：框架结构，抗震设计，荷载计算，内力计算，计算配筋ILuoyangCityWestofficebuildingABSTRACTThisworksforthecityofLuoyangWestofficebuilding,aframeworkstructureforasix-storeymain,intheregionearthquakeintensityof8degreesnearLansiteclassificationasClassIIvenues.Ledtothesouthwestdirection,thebasicPressure0.40KN/M,basicsnowpressure0.25KN/M.Floorroofwereusingcast-in-placereinforcedconcretestructure.Thedesignandimplement"practical,security,economic,aesthetic,"thedesignprinciples.Withthearchitecturaldesign,designseriouslyconsidertheinfluenceofthevariousfactors.Accordingtothestructuralandarchitecturaldetailandtheoverallrelationship.Thedesignofthemainstructureoftheprogramhorizontalframework12-axisseismicdesign.Indeterminingthedistributionframework,thefirstlayerofrepresentativevalueoftheload,Thenusevertexfromthedisplacementmethodforearthquakecycle,andthenatthebottomofshearhorizontalseismicloadcalculationundersize,thencalculatedthelevelofloadundertheInternalForces(bendingmoment,shearandaxialforce).Thencalculateverticalload(constantloadandliveload)undertheInternalForces.Identifythemostdisadvantagedgrouporaninternalforceseveralcombinations.SelectthebestsafetyresultsofthereinforcementandMapping.Inaddition,thestructureoftheprogramindoorstaircasedesign.Completionoftheplatformboards,boardsoftheladder,platformbeamcomponentandthereinforcementofinternalforcescalculationandconstructionmapping.Onthefloorreinforcementcalculation,theuseofpilefoundationdesign,foundationandpilecapsfortheforceandreinforcementcalculation.Thewholestructureofthedesignprocess,instrictcompliancewiththerelevantprofessionalstandard,referencetorelevantinformationandthelatestnationalstandardsandspecifications,anddesignofthevariouscomponentsofacomprehensivescientificIIconsiderations.Inshort,application,security,economicanduser-friendlydesignistheprinciple.Designreasonableandworkablestructureoftheprogramistheconstructionsiteoftheimportantbasisfortheconstruction.KEYWORDS:FrameStructure,SeismicDesign，LoadCalculation，Internalforcecalculation，CalculationreinforcementIII符号－混凝土弹性模量；C20－表示立方体强度标准值为20N/的混凝土强度等级；N－轴向力设计值；M－弯矩设计值；V－剪力设计值；A－构件截面面积；I－截面惯性矩；－永久荷载标准值；－可变荷载标准值；－永...
