石家庄市天宫学术交流中心结构设计

石家庄市天宫学术交流中心结构设计摘要本文以六层公共建筑为设计对象，建筑总高度21.9米，室内外高差450毫米，主要包含建筑设计、结构设计和抗震设计三部分内容。在建筑设计方面，通过综合考虑建筑规范要求与实际使用需求，完成了包括平面功能布局、立面造型设计以及楼梯电梯等垂直交通系统在内的整体方案设计。结构设计方面采用理论与实践相结合的方法，首先在概念设计阶段完成了结构体系选型、平面布置、楼盖系统设计以及基础形式选择等工作。通过详细计算分析，确定了框架结构尺寸，计算了重力荷载和抗侧移刚度，分析了水平与竖向荷载作用下的结构内力，并据此完成了构件截面设计、基础结构设计以及楼梯和楼板的专项设计。为验证设计方案的合理性，研究过程中运用PKPM软件建立了三维有限元模型进行辅助分析。整个设计过程始终贯彻安全可靠的设计理念，通过系统化的设计方法，既满足了建筑使用功能需求，又确保了整体结构的稳定性和安全性，为同类建筑的设计提供了有价值的参考。关键词：截面设计：结构布置：抗震性能：施工图设计ABSTRACTIn this paper,a six-storey public building is designed with a total height of 21.9 meters anda height difference of 450 mm between indoor and outdoor,mainly including three parts:architectural design,structural design and seismic design.In terms of architectural design,theoverall scheme design including plane function layout,facade modeling design,and verticaltransportation systems such as stairs and elevators was completed by comprehensivelyconsidering the requirements of building codes and actual use requirements.In terms of structural design,the method of combining theory and practice was adopted,and thestructural system selection,plane layout,floor system design and basic form selection werecompleted in the conceptual design stage.Subsequently,through detailed calculation andanalysis,the dimensions of the frame structure were determined,the gravity load and lateralstiffness were calculated,and the internal forces of the structure under horizontal and verticalloads were analyzed,and the cross-section design of the components,the design of the basicstructure,and the special design of stairs and floor slabs were completed.In order to verify therationality of the design scheme,a three-dimensional finite element model was established byPKPM software for auxiliary analysis during the research process.The whole design process has always implemented the design concept of"function first,safe andreliable",and through systematic design methods,it not only meets the functional requirementsof the building,but also ensures the stability and safety of the overall structure,which provides avaluable reference for the design of similar buildings.Key words:Section design;Structural arrangement;Seismic performance;Construction drawingdesign目录第1章绪论.1.1研究意义1.2选题背景.1.3国内外研究现状1.3.1建筑设计.1.3.2结构设计…21.3.3抗震设计要点..41.3.4BM技术在结构设计中应用.51.3.5设计难点及解决办法5第2章工程概论72.1建筑基本信息….72.2工程概况….2.3设计依据.7第3章建筑设计83.1平面空间组合设计3.2立面设计….83.2剖面设计.…9第4章结构设计…..114.1结构设计资料.4.2梁板柱截面设计..114.2.1梁截面设计...114.2.2板截面设计..124.2.3柱截面设计.124.3结构布置原则…..14第5章荷载计算.…。155.1计算简图..155.1.1平面计算单元.155.1.2板类型判定….155.2恒荷载标准值计算175.2.1楼面屋面板荷载计算.175.2.2梁柱自重….185.2.3内、外墙自重….185.2.4女儿墙自重.195.2.5板传恒荷载计算..195.2.6梁线恒荷载计算…205.2.7柱点荷载计算.215.3楼面和屋面活荷载标准值…..225.3.1板传活荷载计算.235.3.2梁活荷载计算…245.3.3柱点活荷载计算.…24第6章竖向荷载作用下内力计算…256.1竖向荷载计算256.1.1计算弯矩分配系数….256.1.2计算恒荷载作用下固端弯矩。306.1.3计算活荷载作用下固端弯矩.316.2内力计算…326.2.1弯矩分配计算326.2.2荷载跨中弯矩计算356.2.3荷载柱端剪力计算396.2.4梁端剪力计算…436.2.5柱轴力计算48第7章水平地震作用下框架内力计算.5671水平地震作用下框架结构侧移567.1.1重力荷载代表值计算..567.1.2各层重力荷载代表值计算…..577.1.3结构基本自振周期计算.597.2水平地震作用下框架结构内力计算…607.2.1水平地震及层间剪力计算...
