I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IILuoyangCityWestofficebuildingABSTRACTThisworksforthecityofLuoyangWestofficebuilding,aframeworkstructureforasix-storeymain,intheregionearthquakeintensityof8degreesnearLansiteclassificationasClassIIvenues.Ledtothesouthwestdirection,thebasicPressure0.40KN/M,basicsnowpressure0.25KN/M.Floorroofwereusingcast-in-placereinforcedconcretestructure.Thedesignandimplementpractical,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.IIIThewholestructureofthedesignprocess,instrictcompliancewiththerelevantprofessionalstandard,referencetorelevantinformationandthelatestnationalstandardsandspecifications,anddesignofthevariouscomponentsofacomprehensivescientificconsiderations.Inshort,application,security,economicanduser-friendlydesignistheprinciple.Designreasonableandworkablestructureoftheprogramistheconstructionsiteoftheimportantbasisfortheconstruction.KEYWORDS:FrameStructure,SeismicDesign，LoadCalculation，Internalforcecalculation，CalculationreinforcementIV符号cE－混凝土弹性模量；C20－表示立方体强度标准值为20N/2mm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；kG－永久荷载标准值；KQ－可变荷载标准值；G－永久荷载分项系数；Q－可变荷载分项系数；ekF－结构总水平地震作用标准值；EeqGG、－地震时结构的重力荷载代表值、等效总重力荷载代表值；T－结构自振周期；RE－承载力抗震调整系数；－构件长细比；akf－地基承载力特征值；0H－基础高度；d－基础埋置深度，桩身直径；－土的重力密度；k－风荷载标准值；nF－结构顶部附加水平地震作用标准值；u－楼层层间位移；e－偏心距；svA－箍筋面积；B－结构迎风面宽度；0h－截面有效高度；VSA－受拉区、受压区纵筋面积。目录前言············································错误!未定义书签。第1章工程概况·····························错误!未定义书签。第2章结构布置及计算简图·············错误!未定义书签。§2.1结构布置及梁,柱截面尺寸的初选·错误!未定义书签。§2.1.1梁柱截面尺寸初选···········错误!未定义书签。§2.1.2结构布置························错误!未定义书签。§2.2框架计算简图及梁柱线刚度···························6§2.2.1确定框架计算简图·································6§2.2.2框架梁柱的线刚度计算···························8第3章荷载计算···················································8§3.1荷载计算····················································8§3.1.1屋面及楼面恒荷载计算························9§3.1.2屋面及楼面活荷载计算··错误!未定义书签。§3.1.3梁，柱，墙，门窗重力荷载的计算·······9第4章框架梁柱的线刚度计算······························12§4.1框架梁柱的线刚度计算·········错误!未定义书签。§4.1.1框架梁柱的线刚度计算·····················13§4.1,2梁柱的线平均刚度比························13第5章横向水平荷载作用下的框架内力计算·错误!未定义书签。§5.1重力荷载代表值计算··············错误!未定义书签。§5.1.1墙自重················································16§5.1.2梁，柱，墙，板，门窗重力荷载标准值···19§5.1.3集中与各楼层处的重力荷载代表值计算···21§5.2水平地震作用下框架内力合侧移的计算··········23§5.2.1横向自振周期·······································23§5.2.2水平地震作用··················错误!未定义书签。VI§5.2.3水平地震作用下框架内力计算错误!未定义书签。§5.3横向凤荷载作用下框架结构内力和侧移计算错误!未定义书签。§5.3.1凤荷载标准值··················错误!未定义书签。§5.3.2风荷载作用下的水平位移验算·············35§5.3.2凤荷载作用下的框架结构的内力计算···35第6章竖向荷载作用下内力计算·····························42§6.1框架结构的荷载计算································42§6.2.1板传荷载计算···································42§6.2恒荷载作用下框架的内力··························45§6.2.1恒荷载作用下框架的弯矩计算·············49§6.3活荷载作用下框架的内力··························55§6.3.1活载作用下的框架内力······················55§6.3.2活荷载作用下框架的内力计算·············55第7章框架结构的内力组合··································64§7.1框架结构梁内力组合···········错误!未定义书签。§7.1.1框架结构梁的内力组合·错误!未定义书签。§7.1.2梁端弯矩控制值································74§7.1.3梁端截面组合的剪力设计值调整·········86§7.2框架结构柱的内力组合·····························86§7.2.1框架结构柱的内力组合······················86§7.2.2柱端弯矩设计值调整························102§7.2.3柱端截面组合的剪力设计值调整·······104第8章框架柱正、斜截面配筋计算······················105§8.1框架柱的截面设计·································105§8.1.1框架柱截面设计······························105§8.1.2柱斜截面受弯承载力计算·················119§8.2框架梁的正，斜
