钢结构纯框架体系高层住宅计算书.doc

[中文摘要]：钢结构是目前世界上发展迅速并且应用广泛的建筑结构形式，钢结构在中国将来成为最主要的结构形式已成为可能。目前探讨新农村的建筑形式是个热点，本设计旨在为新农村的建设提出建筑方案，设计了一11层的板式高层住宅，结构方案采用钢框架。该建筑的同一个建筑方案采用了三种柱截面形式，比较这三种方案的优缺点。为完成这项设计我做了以下工作。确定建筑方案，进行结构的分体系设计。采用平面结构分析模型，选取一榀横向框架，初选框架构件截面，计算该榀框架的各种内力，进行内力组合，选取其中最不利组合，验算结构的整体稳定性，构件的承载力，构件的稳定性。再进行节点设计，选典型节点，设计构件的连接方式，验算节点的强度。设计出基础，验算基础的承载力。本设计中采用H形钢柱，再参考同组人采用箱型和圆钢管的柱截面的数据比较，得出了如下结论：用箱形截面柱和圆钢管截面柱的双向抗弯能力强，但对于板式楼H形截面足以满足这些要求，而且其用钢量较小；对于塔式建筑来说H形截面柱就不合理，其它两种截面较为适合。关键词：钢结构住宅、设计、H型钢Abstract：Steelstructurewhichistheworld'srapiddevelopmentandbroadapplicationformstructures,structuralsteelworkinChinawillbecomethemainformofthestructureispossible.Currentlyexploringnewformsofruralconstructionisahotspot,theruraldesignedforthenewbuildingconstructionprogrammes,thedesignofa11-beamhigh-riseresidential,structuralsteelframeworkfortheintroductionoftheprogramme.Theconstructionofaconstructionprogrammewiththeintroductionofacross-sectionofthethreepillarsformthecomparativeadvantagesanddisadvantagesofthethreeprogrammes.ToaccomplishthisdesignIhavedonethefollowing.Determineconstructionprogramme,thestructureofthesub-systemdesign.HorizontalstructureanalysisusingmodelsasaPinhorizontalframeworkprimaryframeworkcomponentscross-section,thecalculationofthevariousendogenousforcePinframeworkforendogenousforceportfolio,selectthemostadversemixwhocheckedthestructureoftheoverallstabilityofthesupportingcomponents,componentstability.Anothernodedesign,thetypicalnode,linkingdesignelements,whocheckednodesintensity.Designbasis,checkingcomputationsbasedbear.ThedesignoftheH-shapedtubeused,withreferencetoagroupbox-YuanSteelPipeandthepillarcross-sectionofdatacompareddrawthefollowingconclusions:abox-shapedcross-sectionpillarandpillarYuanSteelPipecross-sectionofthetwo-waycapacity,butfortheH-beam,cross-sectiontomeettheserequirements,anditssteeltobeusedbysmaller;TheTowerBuilding,H-shapedcross-sectionpillaronunreasonabletheothertwocross-sectionismoreappropriate.Keywords：residenceofsteelstructure,design,HTypesteel目录TOC\o"1-3"\h\zHYPERLINK\l"_Toc13
