文档介绍：摘要本设计主要是对商业大楼进行结构设计。设计采用钢筋混凝土现浇框架结构,建筑层数为五层,建筑面积约为3860 m2。场地类别为Ⅱ类,抗震设防烈度为8度( 5g), 结构抗震等级为二级。设计包括楼盖、楼板、楼梯、结构、基础等部分。在进行构件截面估算和计算荷载代表值后,进行水平地震作用下结构的侧移验算,接着选取了一榀横向框架进行计算。计算内容包括:框架梁柱线刚度计算;恒载、活载、地震作用下梁端、柱端弯矩、剪力的计算;内力调幅计算、框架内力组合;框架梁柱配筋计算; 基础选取及配筋计算。最后绘制了楼盖结构图、楼梯结构图、框架剖面图及截面图。关键词: 荷载;内力;钢筋;混凝土。 Abstract the design of the main structure design mercial buildings. The design adopts the cast-in-place reinforced concrete frame structure, the building has five floors, building area is about 3860m2. Site for the class II, seismic fortification intensity is8 degrees (), structure seismic grade two. Design includes floor, floor, staircases, structure, part of the foundation. The estimation and calculation load representative ponent section after checking, moving side structure under horizontal earthquake action, then select a frame to calculate. The content includes: the frame beam-column stiffness calculation; calculation of the dead load, live load, under the action of earthquake, beam, column end moment, shear force, internal force calculation; am bination; calculation of frame beam reinforcement calculation basis for selection and reinforcement. Finally draw the floor structure diagram, stairs structure, frame profile and cross-section, basic layout and details. Keywords: load calculation, internal force, reinforcement, concrete, structure design, section design, reinforcement. 目录前言........................................................................................................................................ 1 第一章工程概况.................................................................................................................. 2 工程简介................................................................................................................. 2 施工技术条件......................................................................................................... 2 建设场地施工条件...................................................................................
